Brock Allen Turner, 19, is expected to be formally charged Wednesday with five felony counts, including rape of an unconscious woman, rape of an intoxicated woman and two counts of sexual assault with a foreign object, the Santa Clara County district attorney's office told The Times.
Turner voluntarily withdrew from the university Tuesday, Stanford spokeswoman Lisa Lapin said. He's not allowed to re-register for classes and is barred from setting foot on campus, Lapin said.
Early on the morning on Jan. 18, prosecutors say, two men riding bikes on campus spotted a man later identified as Turner on top of an unconscious woman. Turner ran away, but the pair tackled him. A third person called police.
Turner was arrested, booked into the Santa Clara County Jail and released after posting $150,000 bail, prosecutors said. He's scheduled to be arraigned Feb. 2.
The investigation into the incident was conducted by the Stanford University Department of Public Safety, which turned over its findings to prosecutors.
An Ohio native, Turner was a freshman at Stanford. He swam freestyle and backstroke for the Cardinal, according to the university's online athletic roster. His profile has since been taken down.
The alleged victim was not enrolled at Stanford and was visiting the campus for a party, prosecutors said.
Turner was not a member of a fraternity, said Lapin, explaining that freshmen cannot join fraternities or sororities until the spring.
Turner could not be reached for comment.
