An explosion and fire in an electrical room sent smoke billowing through a bank office building in Lynn, prompting the evacuation of nearly 500 workers.
There were no reports of injuries after the explosion in the basement room at the five-story Eastern Bank building at about 10 a.m. Monday.
Workers went to a gym at the community college across the street to stay warm.
Fire officials say utility workers were working in the building at the time, but the cause of the fire remains under investigation.
