The Special Investigations Unit investigation determined that the 42-year-old man, admitted to hospital under the Mental Health Act with self-inflicted wounds, had injuries that were inflicted before the police arrived, and that the officers did not contribute to his death.
According to a statement released by the SIU, the man tried to escape the ward on Jan. 24, the day after he was first admitted. After fleeing his room and assaulting a nurse, he entered another patient's room, blocked the door, then broke a window in the fifth-storey room. Hospital staff managed to enter the room and grab onto the man after he had climbed through the window and was dangling.
The police arrived on the scene and helped pull the man to safety.
After being injected with a sedative, the man was found not to be breathing. CPR was administered and the man was revived. He was then placed in a critical care unit in serious condition and died on Tuesday.
"Since the information collected indicates that his injuries were caused prior to the arrival of the police and that the officers did not contribute to his injuries and subsequent unfortunate death," said SIU director Ian Scott. "I am closing this investigation."
The SIU is an arm's-length agency that investigates reports involving police where there has been a death, serious injury or allegations of sexual assault.
