HARTFORD, Conn. (WTNH)– The State Capitol building in Hartford was evacuated for a brief time after the fire alarm sounded Thursday morning.

Fire crews responded to the Capitol around 8:30 a.m. after the fire alarm sounded. Fire officials tell News 8 that the incident appeared to be minor, if not a false alarm, but firefighters responded to the building as a precaution.
