A 42-year-old man told police he was walking home from work in the 12000 block of Greywing Square about 10:45 p.m. when he heard gunshots.
The man then realized he had been shot in the upper body. He was taken to Reston Hospital, where he is being treated for non-life threatening injuries, said FCPD spokesman Don Gotthardt.
Police searched for the suspect, described by police as a thin black man wearing all black clothing, via helicopter, K9 and ground units.
The suspect has not been located, Gotthardt said Thursday morning. It is unknown if the suspect and victim know each other, he said.
