A knife-wielding man who was shot dead by police at a railway station may have called officers claiming there was a gunman, a watchdog has said.

David Joyce, 38, was shot at close range by an armed officer at Milton Keynes railway station on April 1 after police responded to reports of a man carrying a gun.
