Regina police say there’s no indication of gang involvement in a random stabbing that left four people injured at a downtown shopping mall.

A 15-year-old boy faces three charges of aggravated assault and one count of assault with a weapon in connection with the multiple stabbing Tuesday night at the Cornwall Centre.

The teen, who cannot be identified, made his first appearance in youth court Wednesday morning, and he was remanded into custody until his next appearance April 29.

At this point, there’s no clear motive for the “spontaneous, unpredictable event,” deputy police chief Bob Morin said at a news conference Wednesday.

“As we conduct our investigation, we are trying to determine what a motivation may be,” he said. “But by and large, we have no idea what the motive is.”

Morin told reporters that authorities do not believe the incident is gang-related.

“We look at every violent offence to see if there is any gang relation to those types of events,” Morin said.

“We can say, certainly at this point, that there’s absolutely no indication that there was gang involvement of any kind in this incident.”

Two police officers who happened to be at the mall as part of their regular downtown patrol heard a commotion and were quickly on the scene. They told the young man to drop the knife, he did and was arrested.

Witnesses say the attack was sudden and that the attacker was wearing a red bandana.

Passersby snapped pictures of the carnage, including one posted to the Internet showing a young man lying in a pool of blood as he was being attended to by emergency workers.

Police say four people, all male, suffered non-life threatening injuries in the attack. Three of the victims were taken to hospital and one was treated at the scene.

Morin told reporters he hasn’t seen an incident like this happen in Regina in his 33 years in law enforcement.

“It’s rare and it’s uncommon, and I just urge people not to be concerned about their safety,” Morin said.

“I want to assure the public that Regina is a safe place to be.”
