Police Detonate Suspicious Boston Device on Marathon Bombing Anniversary

A high voltage fuse that apparently fell off a utility truck triggered a response by the State Police bomb squad to the state Department of Transportation’s Division Six headquarters in Boston, officials told the Boston Globe .

A State Police trooper spotted two objects near the DOT office at 185 Kneeland St., a white high rise familiar to commuters heading into downtown Boston or driving onto the Massachusetts Turnpike.

State Police bomb technicians destroyed one of those objects as a precaution, according to State Fire Marshal Stephen D. Coan’s office, which oversees the bomb squad. As they continued their search, they found a second, similar device with one key difference -- it still had a label on it identifying it as a high voltage fuse.

“The item was rendered safe,’’ Coan’s office said in the statement. “Search of the area revealed an identical item clearly labeled high voltage fuse. Closer examination of the first item that had no label revealed it was also a high voltage fuse. It is believed the items came off of a utility truck.’’
