By Mark Nicol PUBLISHED: 01:09 EST, 25 October 2012 | UPDATED: 20:32 EST, 27 October 2012 Two British soldiers shot dead last week in Afghanistan may have been the victims of a revenge attack by local police. Corporal Channing Day, 25, of 3 Medical Regiment and Corporal David O’Connor, 27, of 40 Com-mando, Royal Marines, were previously thought to have been caught up in a so-called ‘friendly fire’ incident. But after interviewing witnesses and recovering fragments of ammunition, Royal Military Police investigators have ruled out the theory that the pair were shot by British Forces. Killed: Female medic Channing Day, 25, from Comber in County Down, Northern Ireland, has been shot dead while on patrol in in Afghanistan
