Winnipeg police have identified the victim of a fatal stabbing at the Millennium Library on Sunday afternoon.
Tyree Cayer, 28, was killed after what police are calling a verbal dispute that escalated into a physical assault.
Police found Cayer with serious injuries around 4:40 p.m., and despite emergency medical care, he died in hospital.
Three teens have been arrested and remain in custody.
A 14-year-old has been charged with second-degree murder, while two others, 15 and 16, each face a manslaughter charge.
Police said they expect further arrests as the investigation continues.
The library will be closed until at least next week as the city looks at new safety options for staff and patrons.
