A 29-year-old man has been accused of exposing himself to a teenage girl at a Silver Spring bus stop.

At about 8 p.m. Sunday, a 15-year-old girl was sitting at the Metrobus stop at the corner of University Boulevard West and Colesville Road in the Four Corners area when she noticed a man sitting next to her, police said.

The suspect began moving closer to her on the bench until he was directly next to her, and she observed that the suspect's zipper was down and that he was exposing himself to her.

The victim ran and found a police officer in a marked cruiser. The girl provided a description of the suspect, and a short time later, police arrested a man who matched the description.

The suspect, Jose Salvador Castro, was arrested and charged with one count of indecent exposure.
