The New Haven County Courthouse was evacuated at around 11:00 a.m. Wednesday morning due to a bomb threat, according to court personnel. Just after noon, the building was declared safe, and evacuees were allowed to reenter.

The New Haven Police entered the building soon after the evacuation with a K-9 unit and closed off streets within a one-block radius of the courthouse, which is located at the corner of Church and Wall Streets. The state police Emergency Services Unit was also on the scene. Around 100 employees, jurors and onlookers congregated outside.

One juror, John Warner, said he was in the courtroom when the police began evacuating the building. He added that the situation was very unusual.

“I’ve been here a few times,” Warner said. “This has never happened.”

More than half a dozen police officers declined to comment on the incident.
