Jozef Roháč

In April 2011, Roháč was extradited to Hungary, where he faced charges for multiple assassinations: Ferenc Domák, pander in 1996, János Fenyő, media magnate in 1998, and Tamás Boros, maffia boss in 1998. In the latter crime three bystanders were also killed in the explosion. In March 2016 the attorney requested lifetime imprisonment for Roháč in a joint trial of his crimes.

After his release from prison, a DNA sample taken back in 2008 was finally matched with samples left behind by the suspected assassin of Hungarian media mogul János Fenyő in 1998. On May 4, 2011 the Chief Prosecutor's Office in Budapest has launched an inquiry into delays in identifying the DNA after recently refusing to accept an explanation by the National Bureau of Investigation. In Hungary, DNA samples taken from criminals must be automatically matched with unidentified samples taken at past crime scenes. According to the newspaper Népszabadság, it is not yet clear whether the delay was caused by police or another authority.

Jozef Roháč was arrested in Hungary in 2008 on charges of an attempted assassination of businessman Zoltan Seres in June 1997 and finished serving his sentence in October 2010. Roháč's fingerprints were found on the device that dislodged from the bottom of Seres' car and failed to go off. The police could not secure enough evidence for a prosecutor to push for a prepared execution of Zoltan Seres, which would carry much higher sentences, he was only sentenced to 2 years in prison and 3 years of being persona non grata in Hungary. Roháč was released on October 26, 2010.

Jaroslav Toman, husband of future Minister of Labour of Slovakia Viera Tomanová, who worked as a high ranking police officer in Bratislava at that time was one of the engaging policemen and Roháč's bullet allegedly missed him only narrowly. Toman's witness account served as a basis to accuse Roháč of the intent to kill, which Roháč denied. For his actions, Toman was awarded a medal for protecting the borders of the Czechoslovak Socialist Republic. Despite the whole incident was declared a state secret, Toman immediately told his wife. The story was broken by TV JOJ in 2008. When interviewing Tomanová, she declared that her husband was scared of Roháč for the rest of his life and that her whole family was threatened at that time.

Bratislava regional prosecution, complying with the investigator, dropped the charges against Jozef Roháč and Imrich Oláh in 2006 in relation to the murder of Róbert Remiáš.

At the beginning of 2000s a gang known as Takáčovci thrived in the Ružinov borough in Bratislava. Róbert Lališ believed them to jeopardize the illegal activities of his own Sýkorovci gang. After a prominent member of Sýkorovci Peter Havasi died shortly after an assassination attempt in 2004, Lališ, who blamed Takáčovci (although their members have been acquitted in 2016) decided to revenge Havasi by murdering a high-ranking member of their group. He picked Ivo Ružič, however, Ružič usually drove black Mercedes G they believed was armored which made the assassination very complicated. Ružič frequented a bar called Astra so Lališ decided to plant an explosive device next to the entrance and hired Roháč to do this job. For this purpose, Lališ's men even used a hidden camera to record Ružič's patterns of behavior and constructed a door overhang to hide the explosive. But Ružič unexpectedly stopped visiting Astra after the bomb had been planted. Lališ decided to make the assassination preparations at a place called Jadran where Ružič had his office. Roháč observed the place masked as a jogger or cyclist. An equivalent of 2 – 3 kilograms of TNT was magnetically attached next to the back entrance to Jadran. Roháč remotely detonated the explosive device on December 2, 2004, at about 1 p.m. when Ružič approached the door accompanied by his bodyguards. The explosion was so powerful that the whole wall collapsed on Ružič. He and his two bodyguards survived the explosion but suffered multiple serious injuries and partial hearing loss. Another 6 people were injured and 20 cars damaged.

In December 1999, Slovak police interrupted investigation in this case. According to Alena Toševová from the Regional Police Directorship in Bratislava, "investigation was interrupted because there were no findings allowing to press charges against any individuals". Slovak investigators were not able to find out what kind of explosive device was used. It has to be noted that this placement of explosives is unique in Slovakia, in all prior mafia hits using explosives, the device was always placed in the car of the victim or in a car parked nearby.

On May 9, 1998 an explosion equivalent to 5 kilograms of TNT killed Eduard Dinič near Zlaté piesky in Bratislava, some minutes before 8 pm. Dinič was aware his life was in danger and he was already preparing to go into hiding and on this day, he wanted to go play tennis for the last time before heading out of the country. Roháč placed the explosives underneath concrete tiling of the narrow pavement leading to the tennis courts where Dinič was known to cross. The device was remotely detonated at the very moment Dinič was above. Pieces of human tissue were collected by the police from the radius of 150 meters and the blast created a hole several meters deep.

Róbert Dinič openly said that he would seek revenge for his brother's death, but outlived him by only 4 months. He was divorced and regularly visited his ex-wife's house on Pribišová street in Bratislava to pick up or drop off their two daughters. Lališ knew about it and instructed his men to park a van in front of the house to observe Dinič. On October 4, 1998 at about 7:40 pm. Jozef Roháč and Ivan Cupper stormed out of the van and opened fire from their submachine guns at Dinič and his bodyguard Marián Fojtík as they entered Róbert's car. Fojtík was shot 7 times, Dinič 19 times. Both were dead at the scene. The assassins then detonated the van and escaped in another car that was later found charred in a forest near Malacky. With Róbert's death, the Dinič group practically ceased to exist.

On July 2, 1998, Roháč assassinated local mafia boss Tamás Boros in Budapest. Roháč placed the explosives underneath a Fiat vehicle parked outside Aranykéz Street No. 2 in the center of the city. The device exploded when Boros was nearby, killing not only him but also 3 unconnected bystanders (including a 24-year-old woman) and injuring 20 – 25 others including foreign nationals. It was the first time in the history of Hungary that innocent bystanders died in mafia activities. The Budapest Police Headquarters suspected Jozef Roháč and other gang members of committing the attack, however, the investigation ended in 2002 as it failed to provide evidence.

Róber Holub was a young mafia boss from Košice with contacts in the Slovak Information Service. He was active in the whole region of Eastern Slovakia. It is generally believed that the boss of all Slovak bosses Mikuláš Černák was contacted by some of his associates from the region who wanted to seize Holub's lucrative businesses and paid for his assassination. Černák planned to replace Holub with his underboss Karol Kolárik, whom he deemed more loyal. The first attempt to assassinate Holub in the spring of 1997 failed after a group of Černák's armed henchmen got caught by the police while leaving their house to do the job. Following this failure, two mafia hitmen were hired to pose as police officers to lure Holub out of his house and murder him. On their way to Holub's residence, the two noticed a car they thought was following them and decided to abort the operation. The third attempt was carried out on September 22, 1997 by Roháč. He was a pillion passenger on a motorcycle ridden by Alojz Kromka that approached Holub at a gas station in Košice. Roháč pulled out his Škorpion submachine gun, aimed at Holub but the gun jammed. They escaped but Holub recognized Kromka because the two shared passion for motorcycles and occasionally rode together in the past. His gang failed to find him so they kidnapped his brother Ján and tortured him. Ján did not know about his brother's whereabouts nor was involved in any of his illegal activities. After the unsuccessful interrogation Holub's associate Štefan Fabián shot Ján dead.

Černák was growing impatient and decided to set a trap. He invited Holub to Bratislava claiming he would provide him Alojz Kromka's whereabouts. Holub arrived at hotel Danube on September 24, 1997 and in the evening entered the hotel bar to meet Černák. He was seated at one table with Černák and Fabián. All but one of Holub's bodyguards remained outside in their cars and the only one who entered the bar together with Holub and Fabián was quietly taken aside by Černák's people. Several minutes later masked Roháč entered the bar and started shooting at Holub and Fabián from a semi-automatic pistol. Fabián dropped dead on the spot, but Holub survived despite being hit 4 times. Roháč and the other Černák's gang members present at the scene threw their guns in one of the flower pots in front of the hotel and fled. Holub was rushed to Kramáre hospital where doctors saved his life. On October 5 masked Roháč used a ladder to climb up the roof of the hospital. He then walked closer to Holub's room and started shooting at him through the window. Holub died after being hit 4 times in his head. Černák later confessed to organizing the murder.

On February 6, 1997, a group of assassins killed the ruling boss of local mafia Miroslav Sýkora in front of the Holliday Inn hotel in Bratislava. Brothers Eduard and Róbert Dinič expected Sýkora's group to disintegrate soon after the death of their boss and wanted to succeed them as the leading criminal group in Bratislava. They were best known for their racketeering business and for their part in the Privatization in Slovakia under Prime Minister Vladimír Mečiar. But Sýkora's well-respected aide Róbert Lališ immediately replaced him as the new boss of his group. Lališ was aware that their competitors would try to take advantage of Sýkora's death and wanted to demonstrate his determination to keep his group dominant. The Dinič brothers immediately became his main target and Lališ instructed Roháč to carry out their assassinations.

The Deputy Director of Slovak Information Service Jaroslav Svěchota gave the order to assassinate Remiáš to the boss of Bratislava mafia at that time, Miroslav Sýkora. Svěchota knew Sýkora personally, both men met regularly. According to the original lawsuit, Sýkora delegated the hit to Jozef Roháč and Imrich Oláh. According to the head of investigators at that time, they were helped by two other unidentified men, one of them a member of the Slovak Information Service. Roháč placed an explosive device under Remiáš's car, attaching it at the rear axle. The car exploded on Karloveská Street in Karlova Ves, Bratislava on April 29, 1996. The explosion did not kill Remiáš immediately, as evidenced by fumes found in his lungs and witness accounts of hearing him scream, but he did die shortly after.

On November 1, 1996, Hungarian millionaire József Prisztás was gunned down in Budapest as he was getting into his car. The perpetrator has left on a bicycle. Roháč admitted to the assassination in 2018 to Hungarian police. The order came from 1990s prominent Hungarian mafia boss Tamás Portik.

Jozef Roháč was born in Levice, Czechoslovakia and as of today, he still has his official residence listed here. He was one of five siblings and his father was an alcoholic, who beat the children, although not very often. In his own words, his childhood was not particularly happy and he used to get often into fights. Later, he started a career of petty crime: "fights, alcohol, badmouthing the communist regime, policemen and suspended sentences" recalls Roháč in the early 1990s.

Jozef Roháč was one of the organizers of the Leopoldov Prison mutiny in 1990 and he was one of the few prisoners to negotiate directly with the Federal Minister of Interior at that time, Ján Langoš.

Róbert Remiáš, an ex-police officer, was the person through which Oskar Fegyveres communicated in a key political lawsuit of the 1990s Slovakia. Fegyveres was an ex-secret agent who gave testimony in the case of kidnapping of the son of the President of Slovakia, Michal Kováč Jr., into Austria. Fegyveres described the involvement of Prime Minister Vladimír Mečiar and Director of Slovak Information Service Ivan Lexa in this crime. As of 1996, Fegyveres was already in hiding and communicated only through his close friend, Róbert Remiáš.

Jozef Roháč is identified in the Slovak media as Potkan (Rat), his other alias being Čiapočka (Little hood). The following identities have been used by Roháč in the past: Josef Fink; Miloš Lukáč (before 1989); Milan Lupták.

Jozef Roháč committed his first high-profile crime in 1985, in communist Czechoslovakia, when armed, he kidnapped the Deputy Minister of Health to negotiate the crossing of the border to escape from the country.

A career criminal for most of his life, in 1984 Roháč was sentenced to 15 years for terrorism under communist Czechoslovakia for kidnapping the Deputy Minister of Health and attempting to take him out of the country. Later, he became the first prisoner ever to escape from Ilava prison. Soon re-captured, he became one of the organizers of the 1989 Leopoldov Prison mutiny. He was released in 1990 because of a wide-ranging amnesty by President Václav Havel.

Jozef Roháč a.k.a. Potkan (September 6, 1956) is a Slovak criminal, terrorist and mafia hitman, specializing in explosives. He is mostly known for installing the explosive device in the Assassination of Róbert Remiáš and in assassinations of numerous organized crime bosses in Slovakia and Hungary. According to newspaper SME, Roháč had at some point connections to both the Slovak and Hungarian Secret Services. Despite international search by the Interpol, he managed to evade the law for 9 years.
