An man who said he would help a lost woman instead exposed himself, setting off a manhunt in Massapequa Sunday night, police said.
The woman was driving east on Merrick Road when she stopped a man walking near Forest Avenue at 11:40 p.m. She stopped to ask him for directions to the Long Island Expressway.
The man told her that he could show her how to get there and got in the back seat of her car.
She began to drive further east and then North on Ocean Avenue when she looked into the rear view mirror and saw the man pulling down his shorts and exposing himself, police said.
When she pulled over, the man grabbed her by the neck, but she was able to scream and honk the car horn.
Someone in the neighborhood heard causing the man to get out of the car and flee south on Ocean.
The woman wasn't hurt.
A manhunt using police aviation, and dogs, as well as officers on foot, did not turn up the man who is described as a white man about 6-feet tall and 180 pounds.
He was wearing a red shirt and a red bseball cap.
Anyone with information should contact Nassau County Crime Stoppers at 1-800-244-TIPS. All callers will remain anonymous.
