Input: The last ‘Briton’ in Guantanamo Bay has given the first detailed account of how he was tortured in the presence of British agents. Shaker Aamer says his head was repeatedly slammed against a wall while a British officer was in the room. On another occasion, a young British officer in a red beret visited him in a ‘cage’. Both alleged incidents took place on US bases in Afghanistan shortly after his 2001 capture. Mr Aamer’s account is one of the most serious allegations levelled at the security services for ‘complicity’ in the CIA’s notorious torture programme. Lawyers for Mr Aamer – who has been held at Guantanamo Bay for 13 years without charge or trial – say the 48-year-old British resident is being denied freedom to keep a lid on his claims.Shaker Aamer says British officer was in room while he was being torturedThe 48-year-old also claims a young British officer visited him in a 'cage'The incidents are alleged to have happened in US bases in AfghanistanLondoner has been held at Guantanamo Bay for 13 years without charge
