Surrey police shooting victim caught on surveillance video

New surveillance video is shedding light on a man's mental state before he was fatally shot by police in Surrey, B.C., on Sunday.

The 20-year-old man can be seen in the convenience store video, pacing inside the store. According to store clerk Connie Yong, he demanded a knife.

"He was looking for a knife and I said I don't have a knife," she said.

"He was so focused on looking for a knife, something sharp.I thought he was going to get the sharp stuff and then kill someone."

Prior to going into the convenience store, the man was seen screaming and banginghis head against a wall at the Surrey Central SkyTrain station. After not finding a knife at the convenience store, the man went to a nearby Safeway.

Witnesses say the manstole a knife, walked towards the bakery and stabbed himself repeatedly. Police tried to de-escalate the situation, but he was shot and died, the Independent Investigations Office said.

The agency, which provides civilian oversight of serious police incidents, said it will review the convenience store surveillance tape as well as 911 audio and post-mortem exams.

According to Vancouver police, about eightpeople are apprehended daily under the Mental Health Act, and between 30,000 and40,000 calls they receive annually involve people who may be mentally ill.
