Detective Inspector Seabright was in charge of operations during the siege of Coronation Street in December 1970 when an insane Joe Donelli held Minnie Caldwell hostage inside No. 5. He sealed off both ends of the street, front and back except for the Rovers, and tried to talk Donelli out by loudhailer. The US Military Police were also there as Joe was an army soldier who was AWOL and Seabright allowed Sergeant Stevens of that force to go into the back yard of No. 5 to try and speak to him there. Joe fired a bullet through the back window at them for their pains.
