Two schools in the area were briefly locked down following the incident.
Montreal police say four adolescents were stabbed during a Thursday afternoon altercation in a St-Michel alleyway and that two of them have been arrested.
Const. Jean-Pierre Brabant said two 15-year-olds and one 19-year-old are in a hospital and that the two 15-year-olds are under arrest.
All of them are conscious and none of their lives are in danger, Brabant said.
Police were called to the alleyway, near the John F. Kennedy High School and John F. Kennedy Adult Education Centre, around 1 p.m. and found a 19-year-old with upper body wounds caused by a bladed weapon, Brabant said. The 19-year-old was taken to a hospital and was conscious at the time.
Officers searching the scene, near Villeray St. and 10th Ave., then found another 19-year-old with minor wounds to his upper body who did not require hospital treatment, Brabant said.
Police later learned that two 15-year-olds had also been taken to hospitals with wounds from a bladed weapon, he said. Investigators met with them Thursday afternoon and they were placed under arrest.
A witness, who is friends with one of the 19-year-old victims, told The Gazette a kitchen knife was used in the attack.
The witness said the altercation was related to an ongoing conflict between students at the nearby École secondaire Joseph-François-Perrault and students at the adult education centre. He said a group of students from the French-language high school recently came to attack students at the adult education centre.
Two schools in the area — an adult education centre and a high school — were locked down following the incident, but Brabant said the situation at both schools had returned to normal before 3 p.m.
“We don’t yet know all the details of this event, but as a father and public security minister, I find it extremely sad to see young people going though a situation like this. Violence is never the answer,” François Bonnardel said in a statement Thursday afternoon.
