VAUDREUIL-DORION, Quebec (AP) — A stabbing attack in a condominium tower west of Montreal left two women dead and another seriously injured, authorities said Thursday.

Provincial police Sgt. Catherine Bernard said a 44-year-old man was arrested at the scene in Vaudreuil-Dorion in Quebec province. He was hospitalized with non-life-threatening injuries.

Bernard said the suspect was known to police but she wouldn’t give details regarding any connection he had to the three victims. She said all three victims were adults but did not release their ages.

Bernard said many people live in the residential complex and police would be meeting with them as part of their investigation. She said police arrived at the building around noon and set up a security perimeter.
