HAVERFORD TOWNSHIP, Pa. (CBS) — Police in Haverford Township are searching for a man accused of sexually assaulting a woman inside a residence in the early-morning hours of Oct. 16. Police say the incident happened in the Chatham Village area off of Township Line Road.

Police say the victim was awakened by the suspect and then sexually assaulted.

Detectives believe the man entered her home through an unlocked door or window.

The suspect is described as short and stocky, around 5-foot-6, with a “stumpy” build, short legs, a slightly protruding stomach, and with hair appearing to be black with some white.

Police say the suspect was wearing a black T-shirt, camouflage pants, a tiger-striped bandana “in a triangle over his face” and a baseball cap with a similar pattern covering over top of the hat. He looked to be about 50 years old.

Police say this is an isolated incident but residents are concerned.

“It gives me the chills. It just makes me worry, especially about senior citizens because if they live alone they’re defenseless,” resident Elaine Deal.

Officers are advising residents to lock their doors and windows. Police have increased patrols in the area and also reviewing surveillance video.

Anyone with information should contact police at 610-853-1298 ext. 1234.
