Vaughan bank, SIU says: No criminal charges in fatal shooting

The director of Ontario's police watchdog has ruled no criminal charges will be arrested in the last year.

The gunman, 25, at the Royal Bank of Canada branch at the corner of Major MacKenzie Drive West and Dufferin Street, Dec. 13, 2017, the Special Investigations Unit (SIU) said.

"He was carrying a backpack-style bag and alerted the occupants' bank that he had explosives in the bag and attached to his body," the SIU report found.

He ordered everyone to be on the floor and to be armed with a semi-automatic handgun.

The man then locked the entrance to the bank and ordered a worker to tie up everyone inside.

The reports say the man ordered 911 and inform police "unless [they] "The President of the United States, Donald Trump on the phone with him, he would detonate his body-worn explosives."

When officers arrived at the scene, the York Regional Police said they needed "lethal force" to gain control of the situation inside the bank, and they were in control of the situation.

"The situation inside the bank was both volatile and dangerous," the SIU said in the report.

They were taken to prevent the threat when they were able to "get a clear and unobstructed shot."

Four officers shot the man in the head, the SIU said, noting he did not have a chance to return gunfire or detonate the explosives. He died at the scene.

Officers 'acted to preserve the lives of many': SIU

Eight SIU investigators and four forensic investigators interviewed 15 witnesses and six other officers to badess whether there was sufficient evidence to warrant charges against the officers.

"It would have been foolish and reckless for the police officers to risk the lives of the hostages, but the innumerable others in the area who could be injured or killed, by waiting to see if a fired from the weapon in the possession of the Complainant, "SIU director Tony Loparco said in the report.

"I do not know what the police should have had to take."

According to the Criminal Code, Loparco stated, the officers "acted to preserve the lives of many" and therefore the use of lethal force was justified.
