The province's Special Investigations Unit said Friday it had no grounds to charge a Toronto police officer in the death of a man who fell from a downtown apartment building in early January.

Dale Anthony Chatrie, 21, died of his injuries after he fell from a Shuter Street apartment following a confrontation with police on Jan. 6.

According to the agency, a woman called 911 claiming that someone had threatened her with a gun in an apartment unit at 285 Shuter Street.

A number of officers responded to the call and after knocking on the door of the 15th floor unit and hearing a voice inside the apartment, the officers decided to break down the door.

The officer in question kicked in the door and approximately six officers entered the apartment. Inside they found a number of occupants inside the small one bedroom apartment.

However, Chatrie went to the balcony where he either jumped or fell. No gun was found in the apartment.

"I am of the view that the involved officers had the lawful authority to enter the apartment in question without a warrant under the exigent circumstances section of the Criminal Code ...," Ian Scott, the agency's director, said in a report.

"There is no suggestion that anyone was on the balcony with Mr. Chatrie at the time he either jumped or fell. As a result, no involved officer can be held criminally responsible for Mr. Chatrie's demise."

The SIU had assigned six investigators and three forensic investigators to investigate the death. Eleven officers and seven civilians were interviewed.

The SIU investigates reports involving police where there has been death, serious injury or allegations of sexual assault.
