On October 30, 2012 he reported to the 306 Reserve Battalion training camp in Uijeongbu, Gyeonggi Province, to undergo five weeks of basic training, followed by active duty for 21 months.

In February 2007, Leeteuk was placed in the trot-singing Super Junior-T. A year later, Leeteuk became a member of Super Junior-H.

On April 19, 2007, almost two months after Super Junior-T's release of their first single "Rokuko", Leeteuk was seriously injured in a car accident, along with Shindong, Eunhyuk, Kyuhyun, and two managers. When returning home after a recording of the radio show Super Junior Kiss the Radio, they were on the highway when the front left tire burst as the driver was switching lanes. The van ran into the guard rail/median on the driver's side, and skidded for about 30 metres. At some point, the momentum caused the van to flip over on its right side.

While Shindong and Eunhyuk suffered minor injuries, Leeteuk and Kyuhyun sustained more serious injuries, which required both to be hospitalised. Leeteuk had glass shards embedded in his back and above his eyes, requiring over 170 stitches. Leeteuk was discharged from the hospital on April 30, 2007.

Due to this accident, Leeteuk did not take part in Super Junior's debut big-screen production, Attack on the Pin-Up Boys in 2007. He was credited as the panda mascot at the end of the film, while it was later confirmed that it had been Ryeowook who portrayed it throughout most of the film.

In March 2006, SM Entertainment began to recruit new members for the next Super Junior generation. However, this was met with fans' objections and strong opposition to the rotational style (much like popular rotational groups in Japan's pop music industry) that the group intended to be. Thus, plans changed and the company declared a halt in forming future Super Junior generations. Following the addition of thirteenth member Kyuhyun, the group dropped the suffix "05" and became officially credited as Super Junior. The re-polished group's first CD single "U" was released on June 7, 2006, which was their most successful single until the release of "Sorry, Sorry" in March 2009.

Leeteuk has partnered with Eunhyuk as host DJs for KBS Super Junior's Kiss The Radio (popularly known as SUKIRA) since 2006. With the exception of four months from March to June 2011, where bandmate Yesung temporarily replaced Eunhyuk while he was away on promotional activities for Super Junior-M's third EP Perfection.

Leeteuk officially debuted as part of the 12-member project group, Super Junior'05 on November 6, 2005 on SBS' music program Popular Songs, performing their first single, "Twins (Knock Out)". Their debut album SuperJunior05 (Twins) was released a month later on December 5, 2005 and debuted at number three on the monthly MIAK K-pop album charts.

When Leeteuk traveled to Apgujeong-dong for sightseeing in early 2000, he was recommended by a talent scout to audition for SM Entertainment's Starlight Casting System. After several test recordings and performances, he signed with SM Entertainment and became a trainee. That same year, he appeared as an extra in the MBC Korean drama All About Eve, and briefly as a model for Pepsi in 2002. In 2003, he was put into five-member boyband Smile, with future bandmate Donghae and aimed to be a rival group of TVXQ. The project was dropped and they were then put into rotational group Super Junior along with ten other boys. Being older than the other trainees, Leeteuk became the leader of the group.

Park Jeong-su (born July 1, 1983), known professionally as Leeteuk, is a South Korean singer, songwriter, presenter, radio personality and actor. At the age of sixteen, he was discovered by SM Entertainment and became a trainee at SM Entertainment's Starlight Academy.
