A young man has three times broken into the apartments of women in an Arlington complex and watched them sleep, according to police. In one particularly disturbing instance, the man approached a sleeping woman and rubbed her arm.

The three incidents all occurred in the same building on the 1400 block of N. Taft Street, police spokesman Dustin Sternbeck said. Two occurred on Sept. 15 and the third on Sept. 21. The suspect is described as a white man in his mid-20s, between 5’10” and 6 feet tall, with medium-length brown hair, wearing jeans and a polo shirt.

Sternbeck said authorities are not sure if the man is a resident or has gotten access to the building in some other way. He could have an access key through his job, or he could be walking in after residents who leave the door open, Sternbeck said. The doors in the building lock automatically when closed but do not deadbolt automatically.

The man has not been caught on any security camera footage.

One victim told WJLA that she awoke to find the man staring at her on the night of Sept. 15.

“ I felt like I was trapped in my bed because he was blocking my bedroom door,” she said. The victim told WJLA that she screamed; the man stared at her and eventually left.

The incident was particularly terrifying, she said, because the doors in the building lock automatically. But Sternbeck says the police have received “conflicting reports” on that count. In any case, they are urging residents to deadbolt their doors at night.
