Authorities are looking for a man they say exposed himself Tuesday morning to two female students on their way to Taylor Middle School, the San Mateo County Sheriff's Office said.
The students reported that they were walking near the upper parking lot at the school about 10:40 a.m. when they saw a man standing outside a car who had his pants down and was masturbating while making eye contact with them.
The students began to run to their classrooms and said that when they looked back the man and vehicle were gone. They reported the incident to school officials.
Millbrae Police Bureau deputies searched surrounding areas and stopped by local schools, but could not locate any suspects or vehicles matching their description.
The man is described as a light-skinned black or Hispanic male, about 5 feet, 8 inches tall, and 20-to-30 years old with a gray or white sedan, possibly a Honda.
"The Sheriff's Office encourages parents and guardians to discuss these types of scenarios with their children to have a plan in place in the event of any encounter with strangers with unknown motives," the office said in a statement.
Anyone with information about the incident or other unreported related incidents is asked to contact Detective Jerri Cosens at (650) 363-4347 or the San Mateo County Sheriff's Office Anonymous Tip-Line at (800) 547-2700.
