Since May, Cleveland Heights Fire Inspector Steve Martin said there have been four suspicious fires in the Belmar, Eddington and Mayfield neighborhood.
The most recent fire was reported at 7:35 p.m. Aug. 25 on the 1700 block of Belmar Road in a garage.
Fire was at the fire and said that no one was injured. The fire started in an empty, two-car garage. Crews stopped the spread, but the structure collapsed several minutes after firefighters arrived, he said.
Martin said though none have been ruled arson yet, in all cases it is clear someone started the fire, but the department still needs to confirm whether it was accidental.
Martin said he couldn't go into details about how the blazes began because the fire and police departments are still investigating the incidents.
"Those have been investigated individually, and now we’re looking at it as a whole package because it may be possible they were all set by the same individuals," he said.
All of the fires started in the early evening on porches or garages, he said.
