Belmont police have released a security camera image that might show a suspect who allegedly exposed himself to a woman last weekend.

The woman was walking on Hiller Street near Marine View Avenue around 3:30 p.m. Sunday when a man pulled up in a car and asked for directions, police Lt. Patrick Halleran said today.

When the woman walked over to the car, however, she saw that the driver had exposed himself. The woman turned and walked away, and the suspect drove away south on Hiller Street, Halleran said.

The suspect is described as a heavyset man in his early 20s who has a medium complexion and was clean shaven with short straight dark hair. He spoke English without an accent and wore oversized, square black sunglasses.

The car was described as a dark red, early 1990s model Toyota Camry.

Investigators have obtained an image of a driver and vehicle consistent with the suspect description from a security camera mounted on a home in the neighborhood, Halleran said.

The person in the photo is described as a person of interest at this time.

Anyone with information about the suspect and vehicle is asked to call Belmont police at (650) 595-7400 or the crime tip line at (650) 598-3000.
