OTTAWA (AFP) - Five people died overnight in a stabbing rampage at a house party marking the end of university classes in the Canadian city of Calgary, media said on Tuesday.
Police were reportedly called around 1:30 am to a home in a quiet suburban neighbourhood where paramedics found three people dead. Two more died in hospital.
Public broadcaster CBC said all of the victims - four men and one woman - were in their late teens or 20s.
"Thoughts and prayers of all Calgarians are with the young people we lost this morning, their families, friends, and university community," Calgary mayor Naheed Nenshi said in a Twitter message.
A suspect was arrested after a chase involving police dogs, the CBC said.
