Arson investigators have been called in after a fire broke out overnight in an abandoned building in LaSalle.
Firefighters were called to the Sterling Street building just before 1 a.m. Wednesday.
"Firefighters, once on the scene, contained the fire pretty quickly,” said Const. Anie Lemieux of the Montreal police.
She said they determined the fires were set in several spots at the scene.
“We don’t know how exactly these fires [were] lit up,” she said.
Police are now looking for witnesses and have no suspect descriptions.
