Smoky two-alarm fire forces evacuation of Post Office Square building

The Boston Fire Department reports firefighters responded at 9:48 to a fire in a basement electrical vault at 10 Post Office Square that was sending smoke up into the rest of the building.

After firefighters were unable to identify the circuit that was causing the problem, the building's occupants - and the firefighters themselves - were ordered out to await the arrival of an Eversource crew that could shut the power to the building from the street.

The department reports the power was shut off around 11 p.m. and with that, firefighters were able to clear the smoke from the building.
