​Metro Transit Police arrested a 19-year-old Maryland man for allegedly fondling and taking upskirt photos of a woman as she was leaving the Columbia Heights Metrorail Station last week, authorities said.

Brandon Lynn Williams, 19, of Forestville, Md., was arrested over the weekend on an initial charge of misdemeanor sexual abuse stemming from the incident. The victim reported that she was using the ascending escalator at approximately 7:50 p.m. Wednesday when she felt a hand up her skirt. The victim immediately left the area, while the suspect returned into the station.

MTPD deployed casual-clothes officers at Columbia Heights and other stations in an attempt to locate the suspect and other potential victims. Meanwhile, investigators were able to find the incident on video and obtain images of the suspect. The review of video footage revealed that the suspect placed a cell phone up the victim’s skirt, MTPD said.

After police released the suspect’s photo last Friday, an anonymous tip led police to identify the suspect as Williams. Officers executed a search warrant at a house in Prince George’s County, where they seized cell phones, computers, and hard drives.

Other victims have been identified and contacted by investigators, but dozens of others may remain unaware that Williams took upskirt photos of them while on an escalator including other incidents at the Columbia Heights and U Street station on Aug. 2 and Aug. 3. All of the victims were females wearing skirts.

Police have urged other potential victims to come forward. To reach the MTPD Criminal Investigations Division, call 301-955-5000, text “MyMTPD” (696873) or use Metro’s online harassment portal at wmata.com/harassment.
