Metro Transit Police this afternoon released a photo of a person of interest in an investigation into an indecent exposure incident.

The incident happened on early Saturday morning, when a man allegedly exposed himself on a Green Line train to a woman, Metro spokesperson Dan Stessel told the Post. Stessel also said that police have reason to believe that this isn’t the first time the man has flashed someone on the Green Line.

According to the release, the individual is known to use the Green Line, and may enter and exit via Greenbelt Station. There is not currently a warrant out for his arrest.

Police urge anyone with information to call 202-962-2121 and reference case #2016-00651. Tips also can be sent via text message to “MyMTPD” (696873).
