A scandal involving systematic physical, mental and verbal abuse of asylum seekers in British detention centres is being investigated amid calls for the government to create a new watchdog to monitor the welfare of detainees. A middle-aged Kenyan woman was alleged to have received facial injuries after apparently resisting being put on a flight by her 3 escorts from a detention centre. Reports say passengers on the Kenyan Airways plane told immigration officials they were shocked to see Bernice Wairimu Mamau's swollen face and cheeks.
