MARTINEZ (CBS SF) — Contra Costa County sheriff’s deputies arrested 27-year-old Christopher Yang in Walnut Creek last Thursday morning on an outstanding warrant on suspicion of sex crimes against a minor, sheriff’s spokesman Jimmy Lee said.
The Walnut Creek man was taken to county jail in Martinez that morning and released later Thursday night on $390,000 bail, Lee said.
Prosecutors charged him with four felony counts of unlawful sexual intercourse with a minor, two counts of sexual penetration of a minor and three counts of oral copulation of a minor, according to the Contra Costa County District Attorney’s Office.
He is set to return to court in Martinez for arraignment on May 20.
Senior deputy District Attorney Nancy Georgiou said Yang at one time worked as an assistant water polo coach at Northgate High School, located at 425 Castle Rock Road. She said she did not know whether he is still employed at the school.
Neither school administrators nor Mt. Diablo Unified School District were available for comment Wednesday afternoon.
