March 24 (UPI) — Authorities in Washington, D.C., are hunting for at least two suspects after a U.S. Park Police officer was shot while on undercover duty in the nation’s capital.

The shooting occurred at about 7:30 p.m. EDT Monday near the 5000 block of Queens Stroll Place SE and the 4600 block of Hillside Road SE, the Metropolitan Police Department said in a statement.

U.S. Park Police Deputy Chief Scott Bretch told reporters in a press conference that the officer was riding in an unmarked police car as part of an ongoing U.S. Park Police investigation when the office was “ambushed” by at least two gunmen.

The officer was struck by gunfire, he said. Authorities said police did not return fire.

Bretch said the police vehicle continued down the street until it pulled over, where the wounded officer received first aid before being airlifted to the hospital with non-life-threatening injuries.

Bretch would not say what kind of investigation U.S. Park Police was working on or how the suspects fled the scene. It was unclear how many police officers were in the targeted police car.

Interim Metropolitan Police Chief Jeff Carroll said that they believe the suspects had targeted the U.S. Park Police officer in the vehicle for being law enforcement.

Authorities are searching for two suspects both described as Black males. One was dressed in a white hoodie with blue jeans, and the other was dressed all in black with a white stripe down his sleeves and pant legs.

D.C. Mayor Muriel Bowser said she had been briefed on the shooting.

“Our prayers are with the officer for a quick recovery and we are grateful for all our law enforcement officers and first responders for their quick response,” she said in a statement.

Attorney General Pam Bondi said she was also briefed on the shooting by Bowser and Carroll, stating the FBI and other federal law enforcement agencies will assist the Metropolitan Police Department “in any way we can.

“Please pray for the officer’s recovery,” she said.
