A townhome fire on Monday morning is being treated by Bellevue police and fire as suspicious.

The Bellevue Fire Department responded to a fire on a six-unit row of connected townhomes at Harmony at Madrona Park in the 2600 block of 139th Avenue Southeast.

Firefighters knocked the fire down quickly, keeping it mainly to the exterior with one attic damaged. Two of the six units were directly damaged by fire, smoke and water. The other four units were impacted as well, as Puget Sound Energy cut power to all the residences.

According to Brian Gomez, the Bellevue Fire Department’s public information officer, fire investigators found evidence the fire may have been set intentionally.

Fire teams turned it over to the Bellevue Police Department, which is treating the fire as “suspicious.”

Police spokesman Seth Tyler said with the evidence that the fire may have been intentional, it was being treated as a crime scene. The homes were opened to the residents on Tuesday.

The American Red Cross provided assistance to the 14 residents displaced by the fire. The initial estimate of damage from the fire is $200,000.
