Mykola Melnychenko

In October 2012, Melnychenko was briefly detained and then released by the law enforcement services of Ukraine.

On July 29, 2011 the criminal case against Melnychenko originally closed on March 1, 2005 was reopened. In October 2011 an arrest warrant against him was issued for "evading investigation and preventing the establishment of truth". According to Ukrainian press Melnychenko was living in the United States at the time, while he claimed he was in Israel; he said he lived there because "there was a plan to physically exterminate me". In late March 2010 the investigation into Melnychenko was suspended because his location had not been established (Melnychenko himself claimed he was living in the United States).

Melnychenko tried to run in the 2010 Ukrainian presidential election but was not registered as a candidate because he did not pay the mandatory election deposit of 2.5 million hryvnya.

On December 6, 2009 Melnychenko accused Volodymyr Lytvyn of ordering the murder of journalist Georgiy Gongadze in 2000. A spokesperson for Lytvyn dismissed the claims as part of the 2010 Ukrainian presidential election campaign.

On March 1, 2005 the criminal case against Melnychenko for "the disclosure of state secrets, abuse of office and using counterfeit documents" was closed.

In 2004, Volodymyr Tsvil, a Ukrainian businessman and former KGB officer who supposedly assisted Melnychenko in his escape and further accommodation in the West, publicly accused him of not revealing certain details of the case.

Nevertheless, experts and politicians analyzing the recordings agree that at least some of them are real, judging by known voices, speaking manners and confidential details mentioned. A few politicians, including Kuchma himself, have officially claimed they recognize their own voices on the tapes. However, the President and his supporters have always denied the authenticity of the body of conversations recorded, calling them a "montage". On the other hand, in 2002 Bruce Koenig, of the US forensic firm Bek Tek, a former worker in the FBI's forensic laboratory, examined the recordings and concluded that there were no signs of them having been doctored.

On November 28, 2000, Ukrainian politician Oleksandr Moroz publicly accused President Kuchma of involvement in the murder of Gongadze, naming Melnychenko as the source of information and playing selected recordings to journalists, starting the 'Cassette Scandal'. Days earlier Melnychenko had fled Ukraine to Ostrava in the Czech Republic, where he left several bags containing dozens of CDs storing thousands of digital recordings. Melnychenko left Ukraine covertly with his family, breaking an official prohibition on leaving the country.

Between 1998 and 2000 Melnychenko allegedly recorded numerous conversations that took place in Kuchma's office before fleeing abroad with the secretly taped recordings. The publication of these recordings in 2000 caused a major scandal in Ukraine (known as the Cassette Scandal), which dramatically affected the country's domestic and foreign policy. Melnychenko's principal accusations against Kuchma (supposedly confirmed by the recordings) are the ordering of the kidnapping and murder of journalist Georgiy Gongadze. The United States government became involved after one of the records revealed the alleged transfer of an advanced Ukrainian radar system Kolchuha to Saddam Hussein's Iraq. Hundreds of other allegations are based on the recordings.

Mykola Melnychenko was born in the village of Zapadynka, Kiev Oblast (now outskirt of Vasylkiv) to a family of coal miners moved from the Donbas. He graduated from the Kiev Military Institute of Control and Signals in Kiev and became a KGB communications protection expert. In 1992, soon after the collapse of Soviet Union, Melnychenko started his career in Ukraine's State Security Administration (formerly the 9th Directorate of the Committee for State Security (KGB)). Later, he joined President Leonid Kuchma's team of bodyguards and at the time of the scandal, Melnychenko held the rank of Major. His main duty was to protect the President's office against possible eavesdropping.

(Major) Mykola Melnychenko (Ukrainian: Микола Іванович Мельниченко , born 18 October 1966 in Vasylkiv, Ukrainian SSR) was a bodyguard of Leonid Kuchma (President of Ukraine), an officer of the State Security Administration.
