LA MESA, Calif. -- La Mesa police were searching Thursday for a man who tried to molest a 9-year-old girl in a park restroom, authorities said.

The man entered the women's restroom at La Mesita Park in the 8800 block of Dallas Street Wednesday, the La Mesa Police Department said in a statement.

The girl was in the restroom using a stall when the man peered under the closed door and asked to see the girls genitals, the statement said, adding he then offered to show himself to her.

After the girl said no, the man left, but he came right back and began peering over the top of the stall, staring at the victim, the statement said.

A woman confronted the perpetrator and began to scream for help, prompting the man to flee, police said.

Witnesses describe the man as white, between 18 and 25, between 5 feet 7 inches and 5 feet 9 inches tall, with short brown hair, brown eyes, a mustache and a goatee. He was seen wearing a black short sleeve T-shirt, tan cargo pants, a black beaded necklace and sandals.

The man's vehicle was described as being a boxy looking turquoise 4-door sport utility vehicle, with partial California license plate number of 4LN.

Anyone with information regarding the man being sought is urged to contact the La Mesa Police Department at (619) 667-1400.
