Over the past several months, motorists have reported a man climbing into their vehicle while they waited at a stop light at the corner of Forest Avenue and Riverside Street, Portland police say.

WCSH-TV reports that police are familiar with the individual and say he suffers from a mental disability. They do not believe the man poses a threat.

“We want to make sure the general public is aware of it and can take actions to protect themselves,” Lt. James Sweatt told WCSH.

Portland police have been receiving calls and tips about the man, who sometimes only tries to open the vehicle’s door but at other times actually gets into the seat.

“In all the situations we have seen there have not been any violent actions…Usually when confronted sternly the individual exits the car,” Sweat said..
