(CNN) —  

An off-duty police officer opened fire Sunday at Pennsylvania authorities dispatched to address a “neighbor dispute,” wounding one officer and pelting several police vehicles with bullets, authorities said.

Doylestown Township police received its call around 1:44 p.m. ET about an apparent quarrel in the community of about 17,500 people, which is located about 30 miles north of Philadelphia, Pennridge Regional Police Department Chief David Mettin told reporters.

About 15 minutes later, a man inside a residence began shooting at approaching authorities.

“One officer has been injured by shrap metal and two police vehicles have been shot,” Mettin said late Sunday afternoon. “And an armored personnel vehicle also was struck.”

Mettin did not give details on the condition of the wounded officer. But he did identify the alleged shooter as Richard Klementovich, a 42-year-old Clifton, New Jersey, police officer.

Sgt. Robert Bracken with the police department in Clifton, which is about 15 miles northwest of New York, confirmed one of its officers is involved in the incident. But he did not identify the department member by name.

He added that Clifton police are on the scene in Doylestown, about 75 miles to southwest, working with authorities there on the matter.

The man was barricaded inside the residence Sunday night, with law enforcement authorities from a host of agencies stationed nearby. Mettin said crime scene and negotiations specialists are among those on site, as are members of the local district attorney’s office and county detectives. He urged local residents to stay inside their homes.

“This is an ongoing incident right now, it changes every few minutes,” Mettin said.
