A police officer was shot and wounded Saturday night and a suspect was also hit in an exchange of gunfire in the District Heights area of Prince George’s County.

The wounds suffered by the officer, a member of the District Heights Police Department, were not believed to be life-threatening, authorities said.

The suspect’s condition could not be learned immediately. County police said that officers had followed a car after a commercial robbery.

Both the officer and the suspect were taken to a hospital after the shooting, which occurred about 9 p.m. on Parkland Court, near Marlboro Pike.

Eddie L. Martin, the vice mayor of District Heights, said in a telephone interview from the hospital that a bullet-resistant vest worn by the officer protected him.

A shot “struck his vest,” Martin said.

Martin said late Saturday that he could not comment further because the matter remained under investigation.

District Heights is a city of about 6,000 near Marlboro Pike and Silver Hill Road, with an area of about one square mile.

It has a 12-member police department, Martin said.

The shooting took place in Parkland Village, a development of two- and three-story brick apartments.

Several residents there said their street, Parkland Court, is generally serene.

“It’s very nice and quiet here,” said one.

One said she heard three gunshots — “pop-pop-pop” — before the arrival of police, who strung crime-scene tape around the area.

The section of Marlboro Pike around the corner from the shooting scene is a commercial strip with small stores and restaurants on each side.

The shooting was the second this week in the Washington area in which an officer was struck.

A D.C. police officer was wounded Tuesday night in an exchange of fire with a suspect in the Trinidad area of the city.
