Boston Fire Department office shut over suspicious mail

The office of the Boston Fire Department’s Fire Prevention Division was evacuated and shut down when an envelope containing a powdery substance was opened early Thursday afternoon, the department said.

Firefighters responded to the fourth-floor office at 1010 Massachusetts Ave. just after 1 p.m., Boston fire and police said. The area where the envelope was opened was isolated and the floor evacuated as crews shut off the building’s air system, Fire Department spokesman Steve MacDonald said in messages posted on Twitter.
