Bridgeport police are looking for the man who brought what appeared to be a hand grenade to the city hall annex, also known as the Margaret Morton Government Center at 999 Broad St., on Tuesday.
Just before 11 a.m., a man gave what appeared to be a disposable coffee cup to a city contractor outside the building and told him that the police internal affairs division was expecting it, according to state police.
The worker obliged and investigators from the office of internal affairs realized that the cup actually held what appeared to be a hand grenade, according to police.
Police evacuated the building for more than two hours.
The bomb squad responded, took the device and determined that it was not active, according to police.
Bridgeport detective have taken over the case.
“We are actively investigating this as a criminal act,” Police Chief Joseph L. Gaudett Jr. said in a statement from police.
