LONDON  - Britain scrapped an inquiry into whether its security services knew about the torture of terrorism suspects overseas, because police have launched a separate investigation into whether London illegally sent detainees to Muammar Gaddafi's Libya. Prime Minister David Cameron announced in July 2010 he was setting up an inquiry, led by retired appeals court judge Peter Gibson, to investigate whether British agents had worked with foreign security services who abused detainees. But the inquiry was barred from examining matters that were before the police, and never formally launched hearings because it was waiting for criminal investigations to conclude.
