Sheriff’s investigators are looking into a report of a rape at El Molino High School in Forestville on Saturday night.

A sheriff’s official said Sunday afternoon that a female victim reported the crime at 9 p.m. The victim told sheriff’s investigators that a man armed with a knife confronted her near the school, officials said.

The suspect walked the victim to the east side of the school’s tennis courts, next to a small shed, where he raped her, officials said.
