Montreal police say first responders found the body of a woman in a home on Fullum Street near the Jacques Cartier Bridge Wednesday morning.
Officers are now investigating that person's death as a homicide and have arrested the woman's son, according to information obtained by Radio-Canada.
Sources not authorized to speak publicly about the case told Radio-Canada police received a 911 call around 9:30 a.m. reporting that the woman was struggling with her son, who was in psychological distress.
Officers who arrived at the apartment on Fullum, near de Rouen Street, in Montreal's Centre-Sud neighbourhood, east of downtown, found the woman unconscious and suffering from stab wounds.
She was declared dead at the scene.
The suspect, a man in his 20s, fled the scene before police arrived, but he was arrested later on Wednesday and questioned by investigators.
Media relations officer Const. Caroline Chèvrefils of the Service de Police de la Ville de Montréal (SPVM) said Wednesday she could not yet provide other details on the victim's identity.
"The scene is now being protected to allow investigators to do their work," Chèvrefils said.
The case has been transferred to the SPVM's major crimes unit.
