Montreal police are investigating a series of small fires in Montreal's southwest.

Const. Raphael Bergeron said fires were set in garbage cans in the LaSalle borough early on Wednesday morning.

"For sale" signs were also set on fire on Villiers Street soon after.

"The damage was controlled very quickly. We're talking about minor damages," said Bergeron.

Bergeron said the wall of a building also caught on fire.

Police have no suspects.
