Deputies arrested a Los Altos High School biology and chemistry teacher Monday night for allegedly having sex with a 15-year-old student on campus after school hours and at his Chino Hills home.

David Park, 37, was booked on suspicion of oral copulation, lewd acts with a child 15 years old and sexual battery. He is expected to be arraigned today at Pomona Superior Court and is being held on $1 million bail.

Hacienda La Puente Unified Superintendent Cindy Parulan-Colfer said a faculty member noticed that the teen seemed very upset Monday afternoon.

The sophomore said she’d been molested by Park since September, according to Lt. Andrew Meyer of the sheriff’s Special Victims Bureau.
