An Arlington gym-goer was followed and flashed after leaving the facility on Saturday, police said today.

Police say a man left the L.A. Fitness on the 3500 block of S. Clark Street, near Potomac Yard, just before 8:00 p.m. He was followed to his apartment by another man. Once inside the apartment lobby, the suspect exposed himself, then fled the scene on foot.

“The suspect is described as a black male in his 30s, approximately 6’1” and 230 pounds,” police said in the daily crime report. “At the time of the incident the suspect was wearing a black knit winter hat, a black hooded sweatshirt with red dots and blue jeans. The investigation is ongoing.”
