Police are looking for a male suspect who exposed himself to a 34-year-old woman while she was walking on the Weston High School track Tuesday night, officials said.
The woman told police she heard rustling from the trees between Route 30 and the track at about 8:30 p.m., according to a statement from Weston police.
She then saw the suspect approaching her with his shorts down. The woman ran to her car in the parking lot and called 911, police said.
Officers arrived at the track and searched for the suspect, but could not find him. A K-9 unit from the Waltham Police Department was called to search the school grounds and surrounding neighborhood, but found nothing, the statement said.
Weston police reviewed a surveillance video of traffic on Route 30 and saw a vehicle making a U-turn and pulling over on the shoulder of Route 30 east at 8:21 p.m.
The driver could not be seen in the video, and the vehicle left a few minutes later, the police said.
Anyone with information on the incident can call Weston police at 781-786-6207.
