On 10 May 2007, Lee was fined S$4,500 and disqualified from driving for three years on charges of drunk driving and other traffic offences, as well as being sentenced to a prison term of four weeks. Lee appealed against his jail sentence but withdrew his appeal later on 28 May. He began serving his sentence at Queenstown Remand Prison on the same day. On 15 June, the prosecution succeeded in appealing against Lee's four-week jail sentence and the court decided to overturn an earlier sentence of a S$3,000 fine for his drunk driving offence. Lee was sentenced to an additional two weeks in prison, making his total prison term six weeks long. On 21 June, the prosecution dropped the last of five charges against Lee for failing to stop after an accident, letting him off with a stern warning instead. Lee was released on 25 June, after receiving a reduction in his prison sentence due to good behavior.
