Washington, D.C. Public Safety

An unmarked U.S. Park Police vehicle was ambushed Monday night in Southeast Washington when two men opened fire on an officer in a white Tesla; the officer was shot in the shoulder, continued driving, pulled over, received first aid, was airlifted to a hospital and has since been treated and released. Metropolitan Police arrested Darren Foster, 21, and Asheile Foster, 22, on charges of assault on a federal officer with a firearm, carried out an armed raid near the scene with K-9 units, and said investigators — including MPD’s NIBIN unit, ATF agents, U.S. Park Police detectives and FBI support — are probing the case amid information suggesting the suspects may have known the victim was an officer, though no motive has been released.
