Randolph man linked to suspicious envelopes sent to Boston police stations

The envelopes, sent to six Boston police stations, turned out to contain ground brown tea from tea bags, but it took the evacuation of a floor at District D-4 on Harrison Avenue and the arrival of the police bomb squad and the fire hazmat team to determine that, police say.

A 59-year-old Randolph man is suspected in connection with the incidents. Police say that, as he has in the past, the man left his name on the envelopes, also sent to police headquarters in Roxbury and districts C-11 in Dorchester, A-7 in East Boston, B-3 in Mattapan, E-18 in Hyde Park and D-14 in Brighton. The envelopes arrived the day after he was committed to the psychiatric unit at Quincy Medical Center, a source says.

In a statement, Boston Police said:

Investigators have identified the sender and will refer that information to U.S. Postal Inspectors. In conjunction, we will determine how to proceed. The threat has been dispelled and the contents of the letter deemed not harmful.
