BANGOR — A standoff between Bangor police and an armed man at a Union Street residence ended peacefully Sunday afternoon, according to police.

Shortly before 2 p.m., Nicholas Condon, 27, of Portland, exited 831 Union St. with his hands up in surrender, according to a news release from Bangor police Sgt. Tim Cotton.

The standoff began after police were called to the Union Street home about 8 a.m. for a report of a family fight, the release said. A man armed with a weapon had entered the residence and taken a man and woman hostage, according to Lt. Bob Bishop.

When police approached the residence, several shots were fired through the wall and door, according to Bishop, and police returned “a couple of bursts of fire.” The officers fell back, called in support and created a perimeter that would last for the next five hours. Police say no injuries resulted from the gunfire.

Negotiators began speaking with the suspect over the phone and convinced him to release the female hostage and later the male. Only the suspect remained inside.

Cotton arrived at the scene before noon and said that he believed negotiators used phones to communicate.

Police said that during the course of the standoff, multiple rounds of tear gas were fired into 831 Union St.

The National Guard had been running drills with helicopters earlier in the morning, but police asked them to stop as the standoff situation unfolded, according to Bishop.

Union Street, which had been closed to at least the Vermont Avenue intersection during the standoff, was reopened after police cleared the area.

Condon is charged with two counts of kidnapping, criminal threatening with a dangerous weapon, reckless conduct with a firearm, burglary and terrorizing, police said. He may face additional charges as the investigation continues.

Investigators from the state attorney general’s office are assisting with the investigation, Cotton said in the release.

Maine State Police, the Bangor Fire Department and the Bangor Public Works department assisted during the incident.
