Police believe a recent fire set to a couple of houses was arson.

At around 3:30 a.m. on Saturday morning (July 23), emergency services were called to a structure fire in the Summerwood subdivision in Sherwood Park. 

Two homes were a complete loss.

"Crews worked fast to protect the third home from exposure," the Strathcona County fire department said on Facebook. 

All homes were unoccupied, newly built units. 

The initial investigation determined the fire was intentionally set as an accelerant was located at the scene. Strathcona County RCMP's General Investigation Service continues to look into the incident.
