Hakop Jack Kaplanyan, 19, appeared at an arraignment hearing on an eight-count indictment. He is charged with one felony count each of forcible rape, false imprisonment by violence, possession of matter depicting a minor engaging in sexual conduct and a misdemeanor count of sexual battery by restraint.
Kaplanyan also faces two felony counts each of sexual penetration by a foreign object and assault with the intent to commit rape, according to a grand jury indictment that was unsealed in court.
Prosecutors say the charges involve three women -- all UCLA students -- in attacks that happened between October 2012 and April 2013.
Kaplanyan was previously arrested in April after a woman accused him of raping her in a campus dorm room, but he claimed the sex was consensual. He was released on $200,000 bail at the time.
While no charges were immediately filed, he was kicked out of school shortly after the arrest.
He was arrested again Friday and was held on $590,000 bail. His attorney asked the judge that the bail amount be reduced, but the request was denied. Kaplanyan was released Monday after posting the bond.
If convicted on all charges, he faces 37 years and four months in state prison. Kaplanyan is expected back in court on April 29.
