A parked car exploded Downtown at 11 am Thursday for no immediately apparent reason, firefighters said.
It took at least 15 firefighters 45 minutes to extinguish the blaze in the trunk of an auto on State Street, according to fire department spokesman Danny Glover.
Smoke eaters responding to a report of a car smoldering found the auto with its engine in flames. There were no injuries and no one was in the car at the time of the explosion, Glover said.
The cause of the flare-up is still under investigation.
