The son of a senior Calgary police officer has been taken into custody following a stabbing rampage at a house party in Calgary Monday night that left five young people dead.

Calgary police say they were called around 1:30 a.m. MT to a home in the residential neighbourhood of Brentwood, where students had held an all-day party.

Five people were found with stab wounds, all of them in their late teens and early 20s. Paramedics declared three men dead at the scene. Two more victims, a man and a woman, were taken to hospital, but later succumbed to their injuries.

About 30 minutes later, police using canine units tracked a suspect in his 20s who had fled the home. The suspect was arrested and taken to hospital for treatment of injuries sustained during the police dog pursuit.

While police have not yet released the suspect’s name, CTV Calgary has confirmed the man is the son of a senior officer with the Calgary police. Police say they are not seeking any other suspects.

Police are also not releasing the names of the victims until their next of kin are notified and autopsies are performed.

It remains unclear what led to the violence as neighbours report they heard no commotion during the night. It’s also unclear how the suspect was connected to the victims.

Neighbours say the students who rented the house had been drinking at the home throughout the day without incident to mark the University of Calgary student union’s annual “Bermuda Shorts Day,” which celebrates the last day of classes.

Doug Jones, who lives across the street from the house where the killings took place, says about a dozen students appeared to be having a barbecue in the home’s backyard in the evening.

“It was like a normal gathering; it wasn’t loud, it wasn’t unruly. Around dusk, they moved inside, and then we didn’t really hear anything,” he told CTV News Channel.

“We woke up this morning to yellow tape in the back alley here. I was in shock when the reporters told us what happened.”

The University of Calgary released a statement to say it is awaiting more information.

“The University of Calgary is mourning the loss of five young people killed early this morning in Brentwood. The identities of the deceased have not yet been confirmed by Calgary Police Services. Once details are confirmed by Calgary Police Services, the university will provide a further statement,” it said.

Five people are dead after a stabbing at a house party in Calgary involving university students.

The victims are reported to include four men and a woman, all in their late teens or early 20s.

The violence erupted at a home in the northwest neighbourhood of Brentwood just before 1:30 a.m. today.

Police say a person who had fled from the home was arrested with the help of a canine unit and later taken to hospital for treatment of dog bite injuries.

There's no immediate word on the motive for the attack.

Neighbours say the home was being rented by University of Calgary students and that they were having a so-called Bermuda shorts day party that started yesterday.
