A Libyan who says he was detained under Moammar Gadhafi's rule has claimed that top-ranking Libyan defector Moussa Koussa directly participated in his torture.
The allegation raises questions about U.S. and European officials' decision to unfreeze the assets of the former Libyan spymaster, whose defection to Britain in March helped destabilize Gadhafi's regime.
The former prisoner, Muftah Al Thawadi, told BBC television that Koussa had shocked him with an electric rod while he was held at Tripoli's Abu Salim prison.
Another detainee told the BBC that Koussa knew of his mistreatment and interrogated him after he was tortured.
The BBC also showed footage of its attempt to get comment from Koussa in Qatar. He shoves a reporter when questioned.
