Police in Loudoun County are investigating a series of exposure cases near Sterling, Va., that they believe are connected.

The latest incident occurred at 10:45 p.m. on Thursday, when a teenage girl said she was standing outside her home in the 230 block of Greenfield Court and observed an unknown man exposing himself.

She described the man as a white or Hispanic male in his mid-to-late teens, about 5 foot 10 inches with a thin build.

Police believe this could be the same man who has been exposing themselves to Sterling residents since March.

On March 31st, a contractor working at a home on Wedgedale Drive said they heard a knock at the door and opened it, but discovered no one there. A few minutes later someone knocked on the door again and, when the worker looked out the window to see who it was, saw a man with a similar description exposing himself.

On April 8 someone called police saying they saw a man exposing himself outside with a similar description.

Police are asking anyone with information about these incidents to call (703) 777-1021.
