A D.C. police officer was shot and wounded Sunday night in Northwest D.C., the Metropolitan Police Department said. Authorities called off a barricade situation, but the shooter remains at large.

The officer’s injuries were not life-threatening, police said. The officer, whose name was not revealed, was taken to a hospital and later released.

The shooting occurred after officers approached a man on the street in the 1400 block of Quincy Street NW, police spokeswoman Kristen Metzger said. At some point during that interaction, the man opened fire, police said.

One officer from the 4th District was struck and taken to a hospital, Metzger said.

Chief of Police Robert Contee III said it did not appear that officers returned fire. He also said they approached the man because he seemed “suspicious in terms of his behavior,” but Contee did not elaborate.

The department previously said the gunman fled the scene and entered a multi-unit building in the area. The entire SWAT team was deployed, authorities said, but the suspect wasn’t found in the building.

“We’ll be out here for a while until we find the person responsible for this,” Contee said.

More information about the suspect and circumstances of the shooting was not provided.
