On October 4, at around 6:15 a.m., police officers from the Beauharnois-Salaberry MRC station were called to the Cégep de Valleyfield after an individual allegedly injured an employee of the establishment.

A perimeter was set up and the premises were quickly secured so that no one could enter or leave the establishment without knowing the individual's intentions.

According to information obtained at the scene, the suspect set fire to the cafeteria as a diversion. At the time of his arrest, the man, whose identity remains unknown, was naked.

He was taken to hospital for treatment and is expected to appear at the Valleyfield courthouse when his condition permits.

The victim was taken to hospital with non-life-threatening injuries. An investigation is underway to clarify the causes and circumstances surrounding this event.

At the time of writing, chemin Larocque and rue Champlain were still closed to traffic. 

Authorities and the Cégep de Valleyfield team recommend avoiding the area altogether.
