Police have released a more detailed description of a man who allegedly abducted a girl as she walked to school in Northeast Washington Thursday morning, and more information about the assault and the vehicle that the attacker was driving.

Authorities had initially said that the girl was freed unharmed after she fought back. On Friday, police said further investigation revealed the 16-year-old was sexually assaulted during her brief captivity.

The incident occurred about 9:20 a.m. as the victim was walking in the 5100 block of Nannie Helen Burroughs Ave. NE, at 51st Street. Police said a man got out of an older model sport utility vehicle that resembled a GMC. Police said the man grabbed the girl from behind and forced her into the vehicle.

A D.C. police spokeswoman said on Thursday that the victim fought back and then pushed or kicked her out of the vehicle after a few blocks. Police said on Friday that the abductor “groped” the girl “before letting her go.”

Police described the man as black, with a light complexion, and in his late 20s, standing 5 feet 7 inches to 5 feet 9 inches tall and weighing about 200 pounds. He has hair braided in long corn rows and crooked teeth. He was last seen wearing a black jacket.

Anyone with information is urged to call police at 202-727-9099 or text the department’s tip line at 50411.
