Up to 30 hospitals are now under investigation as part of the inquiry into Jimmy Savile's alleged abuse of patients at NHS hospitals. Inquiries had originally just focused on Broadmoor and Stoke Mandeville and Leeds General Infirmary. Revelations that Savile had sexually abused children prompted hundreds of victims to come forward, including those who said they were attacked on BBC premises and at a number of other institutions. Savile had a bedroom at Stoke Mandeville Hospital, an office and living quarters at Broadmoor, and widespread access to Leeds General Infirmary. Liz Dux, an abuse lawyer who represents more than 70 of the claimants, told the BBC she was worried the extension would prolong the distress of her clients. These hospitals were known about - all my clients gave their evidence some time ago to the NHS investigation. These victims want the investigation concluded, naturally as efficiently as possible, but they want it over, they need closure," she said. The revelations about Savile have led to a number of inquiries. The police investigation, Operation Yewtree, ... has three strands. One looking specifically at the actions of Savile is due to report in the new year. The BBC understands it will put the number of alleged victims at over 500. The second strand concerns allegations against "Savile and others". The third relates to complaints against other people unconnected to the Savile investigations, made by people who came forward after widespread coverage of the scandal
