BREAKING: Police are blanketing Petworth after an armed carjacking in the 300 block of Taylor St. NW. The perpetrator, a 5’8″ black male dressed in running gear and a ski mask, commandeered the car at approximately 7:50 p.m. and fired on three cops at 7:55, hitting no one. A low-flying helicopter equipped with a searchlight is keeping a tight perimeter around the neighborhood. Residents are being asked to remain in their houses and to report any suspicious behavior to the police.

Further bulletins forthcoming.

UPDATE ~10:50 p.m.: Officer Peterson at the D.C. Police Public Information Office reports that the suspect’s still at large. “He’s still out there,” Peterson said. “He got away.”

More details on the shooting: After jacking the car—a Ford Escape—the perpetrator drove north before encountering three officers at 3rd and Upshur Streets NW. “He took a couple potshots at them,” Peterson said. No one was injured. Police have recovered the car, which the culprit ditched to proceed on foot.

UPDATE ~12:01 p.m. 2/13/09: Officer Kenny Bryson at the D.C. PIO confirms that the shooting happened at 3rd and Taylor NW, not NE. This morning’s Washington Post mistakenly identifies the 300 block of Taylor St. NE as the site of the carjacking.
