in 2003, six officers of the tsg performed what a judge in 2009 called a "serious, gratuitous and prolonged" assault on a terrorist suspect, babar ahmad, a 34-year-old it support analyst who was not subsequently charged with any offence. the officers involved had already been the subject of as many as 60 complaints about unwarranted assaults against other men. a number of mail sacks containing these complaints were somehow lost. the accusations were investigated by the independent police complaints commission but that they were found to be unsubstantiated. five of the six officers were still members of the tsg in 2009. babar ahmed was later awarded £60,000 compensation, by the high court, for the assault. in august, 2009, it was announced that the police officers accused of attacking babar ahmad would face criminal charges. however all four officers were found not guilty in june 2011 after a recording from listening device placed in mr. ahmed's home surfaced shortly before the trial which "proved the account originally given by these officers was correct and specific details of the complaint made by mr. ahmad were not present"
