Classrooms at the University of Bridgeport were evacuated as a precaution after police said a "suspicious device" that appeared to be a pressure cooker was found at Seaside Park Thursday afternoon.
The "unattended item" was located near a tree in Seaside Park around 11 a.m., police said.
The Bridgeport Police Department and Connecticut State Police Bomb Squad were called to the scene. Officers cordoned off the area while the bomb squad investigated the device.
Since it was close to the water, the United States Coast Guard was also called and set up a 200-yard safety zone in the Long Island Sound.
The bomb squad did a "controlled detonation" of the item at 2:45 p.m.
Police confirmed the device was an empty pressure cooker, and it was not a threat to the public because it was empty.
Investigators said they are not trying to figure out if someone left the pressure cooker by accident or if it was intentionally put there to scare people in the wake of what happened in Boston at the marathon bombing.
"Any time we receive a report of a suspicious package, we respond with an abundance of caution," said Bridgeport Police Chief Joseph L. Gaudett Jr. in a statement. "Today's incident was no different. Obviously, considering the incident in Boston, we treated this as a credible threat, followed our protocols and requested the assistance of the State Police."
Three buildings at the University of Bridgeport were evacuated as a precautionary measure after the device was found, school officials said. Students were able to return to those buildings shortly after 3 p.m.
Bridgeport-Port Jefferson ferry service is "very delayed" because of the incident, company officials said.
