LAFAYETTE -- Police are investigating a suspicious encounter between a man and a girl that occurred Monday near the intersection of Hough Avenue and Brook Street.

About 11:45 a.m., a child said a man in a truck appeared to be waving at her to come to his vehicle, which was stopped in the middle of the street, according to the Lafayette Police Department.

The child told her parent who was walking nearby. When the parent walked over to the child, the truck drove away from the intersection.

Lafayette police do not know if the driver was simply saying hello to the child, allowing her to cross the street, or if there were other unknown motives.

The vehicle is described as a newer white pick-up truck with a camper shell over the bed of the vehicle. The vehicle was last seen headed east on Brook Street toward Moraga Road.

Anyone with any information is asked to contact the Lafayette Police Department at 925-284-5010 or through the tip line at 94549Tip@gmail.com.
