A day of partying to celebrate the end of term ended in tragedy in Calgary, where five young people were stabbed to death.
At around 01:30 (08:30 BST) this morning, police were called to an address on Butler Crescent Northwest, in the north-west Brentwood area of the city, where they found five people having suffered stab wounds, according to CTV.
Paramedics declared three young men dead at the scene, with a man and woman succumbing to their injuries later in hospital.
Police used dogs to track a suspect that had fled the scene, who is now in custody.
The motive for the attack remains unclear.
All of the victims were students at the University of Calgary, which issued a statement saying:
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.
