An infant and two other people were seriously injured Wednesday in a hit-and-run accident in Northeast Washington, D.C. police said.

A woman driving a vehicle with two children inside collided with another vehicle on Kenilworth Avenue, at the intersection with Eastern Avenue, just before 5 p.m., said Officer Paul Metcalf, a police spokesman. All three people in the first vehicle were injured.

Police said the driver of the second vehicle got out of the vehicle after the crash and fled on foot.

He was described as black with a medium complexion, about 5’8”, 150 pounds, with braided hair. He was wearing a white t-shirt, red shorts and black sneakers, Metcalf said.

Initially, police officials mistakenly reported that the infant and others were hurt in a pedestrian accident.

Authorities said the infant, whose age and gender were not immediately known, was in and out of consciousness at the scene. The woman and two children were taken to a hospital with serious injuries, Metcalf said.
