Calgary house party stabbing leaves five dead
The son of a policeman has been arrested in connection with the stabbing deaths of five people at a house party in Calgary.
The attack, considered the worst mass murder in the city's history, occurred shortly after 01:00 local time (07:00 GMT) on Tuesday.
The victims reportedly range in age from 22 to 27, and were attending the party near the University of Calgary.
The unnamed male suspect is said to have been a student at the school.
'Thoughts and prayers'
"The scene was horrific," Police Chief Rick Hanson told reporters following the incident.
The suspect - said to be the son of a 33-year veteran of the Calgary police force - was invited to the party where he used a large knife to stab the victims one by one, Mr Hanson added.
Three male victims were reportedly found dead at the home, while a female and male later died at a nearby hospital.
Calgary Police spokeswoman Emma Poole told the BBC the suspect was in his early 20s and was being treated for a dog bite injury.
Charges have yet to be filed against him, as police search for a motive in the attack.
The neighbourhood where the stabbings took place is situated near the University of Calgary, located in the largest city in the western Canadian province of Alberta.
"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 wrote on Twitter following the incident.
