A pedestrian was seriously injured Thursday afternoon when he was struck by a vehicle in an apparent hit-and-run in the Wheaton-Glenmont area, Montgomery County police said.

The incident occurred near the intersection of Centerhill and Edwin streets about 4:50 p.m., police officials said. A witness told police the vehicle was traveling on Edwin Street, went through a stop sign, and then struck the man in the roadway, officials said. Anyone with information is asked to call Montgomery County police.

The victim, described as a man in the late teens, was taken to a hospital with life threatening injuries, said Capt. Oscar Garcia, a spokesman.

Police were looking for a dark blue Nissan Sentra, which may have fled the scene, authorities said.
