A sergeant with the Mesa County Sheriff's office says it was probably the battery in his radar that exploded, setting part of his office on fire.
It happened just before 2:30 a.m. Friday. He says he was sitting in his office when there was an explosion, and a lot of smoke filled the room. A small fire ignited, and the Grand Junction Fire Department was called in.
Fire Department spokesman Mike Paige says the sergeant tried to put the flames out with a fire extinguisher but was unsuccessful
Firefighters got things cleaned up in about an hour. No one was injured in the incident. Officials say damage is estimated at $50,000. About $10,000 in damage was done to the building and about $40,000 in damage was done to the contents of the room.
