CAMBRIDGE - Police and fire crews were called to an abandoned building in Cambridge for two separate incidents of a fire on Sunday.

The building is located at 201 Beverly St. at Dundas Street North.

The first call came around 1 p.m. when officials were sent to the scene due to a minor smoke incident.

Crews were called back around 5 p.m. for a larger fire.

Smoke and flames were seen coming from the building's roof.

Since the building is abandoned and it has no electrical or hydro, police are treating this as a case of arson.

Nobody was in the building at the time of the fire and no injuries have been reported.

Police say there are no witnesses.

Fire prevention is expected to be on scene Monday to further investigate.
