Investigators say a fire that caused about $500,000 in damage is a case of arson.

On May 6th, the Calgary Fire Department was called to a blaze at the 2600 block of 12th Avenue Northwest, in the community of St. Andrews Heights.

Two people inside escaped without getting hurt and crews extinguished the flames.

But the fire investigator determined someone lit the house on fire from the outside.

Calgary police obtained surveillance footage, available below, from a nearby home and officers want Calgarians’ help identifying the suspect.

Anyone with information on this incident or the suspect’s identity is asked to call the Calgary Police Service non-emergency line at 403-266-1234 or to contact Crime Stoppers anonymously using either of the following methods:
