Luger pistol
On 30 November 1989, Warren was to attend one of his boxing promotions at The Broadway theatre in Barking which featured Colin McMillan. As he arrived at the venue he was approached by a masked gunman who appeared from the crowd and shot him twice in the chest with .22 bullets from a Luger pistol at close range. The gunman fled and Warren was taken to hospital. Warren lost half a lung and was in great pain after the shooting.
