A taxi that was stolen during an armed carjacking in Northwest Washington Friday morning was found abandoned 10 1/2 hours later and three blocks from the scene of the attack, according to D.C. police.

The driver, who was stabbed in the side, remained in serious condition at an area hospital, according to authorities. Police were still searching for the assailant late Friday afternoon.

Police said the attack occurred about 6:45 a.m. in the 500 block of Kenyon St. NW. It’s about two blocks east of Georgia Avenue in the Pleasant Plains neighborhood.

Officer Araz Alali, a police spokesman, said a man in his 50s dressed in all black and armed with a knife stabbed the driver and then took his black 2011 Chevrolet Impala owned by the Black Pearl Cab Co.

Police said that while robberies of taxi drivers are fairly common, the thieves rarely take the well-marked cars. Alali said the attacker was last seen driving the taxi east on Kenyon Street.

D.C. police said officers found the taxi about 5:15 p.m. in the 500 block of Hobart Place, between Columbia Road and Harvard St. Northwest.

A manager at the Black Pearl Cab Co. declined to comment when reached Friday morning, saying he had only heard of the incident from a reporter. He said the drivers are all independent.
