Montreal police said they believe more than one suspect was involved.
Montreal Police found a 19-year-old stabbed in a downtown alleyway on Thursday. A 911 call around 11:30 a.m. alerted officers to a possible armed assault near rues Lincoln and St-Mathieu in the Ville Marie borough. A group conflict allegedly got violent and the victim was attacked.
The youth was later found with at least one upper-body injury in an alley near Crescent and Sherbrooke. He was rushed to the hospital, where police say his life is not in danger.
"Officers arrested one suspect, but are looking for a second one," said SPVM spokesperson Mariane Allaire Morin.
A crime scene has been established in the area and police have dispatched a canine team to the scene to gather clues, as police look for the other person possibly involved in the stabbing.
The suspect who is in custody will meet with investigators.
