A Lyon Park woman told police she saw a peeping Tom outside her ground-level apartment window over the weekend.
The woman noticed the voyeur at about 12:39 a.m. Sunday outside her apartment in the 700 block of North Cleveland Street, according to the Arlington County Police Department.
The victim told police she was wearing a bra at the time. She alerted her male roommate, who went outside to confront the peeper.
The suspect was pushing a bike as he walked away from the property, police spokesman Dustin Sternbeck told Patch.
The roommate yelled at the man, who then dropped the bike and ran away, Sternbeck said.
Neither the victim nor her roommate could provide a description of the man to police, Sternbeck said.
