An 18-year-old Danville teen was arraigned Friday on charges that he raped a 14-year-old girl in his van last week, the Contra Costa Times reported.
Prosecutors have charged Sam Nesis, a recent San Ramon Valley High graduate, with forcible rape, forcible oral copulation of a minor age 14 or older and three related felony sexual offenses for an attack authorities said occurred in Nesis' blue 1977 Chevy 1500 van the night between Feb. 18 and 19.
Deputy district attorney Nancy Georgiou declined to release further details about the circumstances out of concern for the victim's privacy.
The California Highway Patrol is investigating the incident because it is said to have begun as the defendant and victim were traveling on a freeway, and continued in the parking lot at the Walnut Creek BART station, CHP spokesman Trent Cross said.
The girl reported the assault and was treated at a hospital early Feb. 19, Georgiou said.
Nesis was referred to the Public Defender's Office and is being held in County Jail on $500,000 bail. He is scheduled to return to court to enter a plea March 3.
Anyone with information about the case can contact CHP investigator Kathleen Hayes at 510-622-4609.
