A 16-year-old is facing an attempted murder charge in connection with a shooting at a downtown Tim Hortons Sunday evening.

Two other people — a 15-year-old and a 23-year-old — are also facing a host of charges stemming from the investigation, Hamilton police say.

"A crime like this is always very disturbing to the community," Chief Eric Girt told CBC News in a statement.

The incident happened just after 6 p.m. Sunday at the corner of Caroline and King Streets. Police say a man at the Tim Hortons at 239 King Street West got into an argument with other people in the parking lot.

We know this level of violence is infrequent and that's why it's shocking. - Police Chief Eric Girt

That was when a teen pulled out a gun and fired a bullet into the restaurant's glass door, police say. No one was injured.

According to a news release, detectives were able to ID the alleged shooter on Monday. He was arrested in the area of Jackson Street West and Caroline Street South. Officers say they found a gun on him when he was arrested.

The teen is now facing charges of attempted murder, 10 firearm-related charges linked to that single gun, uttering threats to cause death, possession of cocaine for the purpose of trafficking, and six counts of breaching a court order.

2 others charged

Police say they also arrested a 23-year-old who was with the teen at the time of his arrest, but who wasn't there when the shooting at the Tim Hortons happened. He has been charged with possession of cocaine for the purpose of trafficking, possession of proceeds of crime under $5,000, breaching his probation and two counts of failing to comply with a recognizance.

Detectives say they also tracked another teenager who was at the Tim Hortons when the shooting happened, but wasn't directly involved.

That 15-year-old was arrested after a "brief chase" on Monday, police say, in the area of George Street and Hess Street South.

He was charged with possession of Percocet and Clonazepam — both of which are controlled substances.

All three people are expected to appear in court Tuesday for bail hearings. One other suspect is still outstanding, police say.

Youth crime down, but violent youth crime rising

Gun violence numbers are surging in Hamilton, with 23 shootings so far this year. That's almost as many as all of 2018, when there were 25.

According to the newest statistics from Hamilton police, youth crime levels dropped at a rate almost triple the national average last year — but violent crime involving young people is actually on the rise.

Hamilton police say 508 young people were involved in violent crimes last year, compared to 473 in 2017. Of those 508 people, 220 were charged with a violent crime, while 56.7 per cent received an "extrajudicial measure" instead.

Girt said that rise in violent youth crime was largely as a result of "low-level assaults."

"We know this level of violence is infrequent and that's why it's shocking," he said.
