Teenage girls walking to and from school in the Tri-Cities are being warned about an older man stopping or slowing his car to make lewd comments and gestures at them. Port Moody Police issued the alert on Monday after a girl was approached by the man last Wednesday - the fourth time police have taken a complaint since early January about such allegations. The lewd incidents happened at bus stops and in residential areas in Belcarra, Port Moody and Coquitlam. "It's just rude, vulgar comments, lots of staring," Const. Todd Lefebvre of PMPD youth services said. "He makes the girls feel uncomfortable." Still, while police have photos of the man's vehicle - a blue 1991 Chevrolet Sprint hatchback - showing his licence plate number, they say he hasn't broken any laws. The man is described as Caucasian, 50 to 59 years old, at least 6' tall with grey/white hair, a moustache and blue eyes; he has been seen wearing jeans and a jean jacket as well as black nylon pants with a brown zip-up fleece jacket and white running shoes. Anyone who is approached by the man is asked to call PMPD, quoting file number 2011-949, at 604-461-3456 or email [email protected] or [email protected]. [email protected]
