Feb 27, 2026
A teacher and coach at Eisenhower High School in Rialto has been placed on administrative leave after police accused him of sexually assaulting at least one child.
No victims have ties to the school, Principal Kristal Pulido said in a message to parents.
Mark Anthony Bibian, 31, was arrested Feb. 12
on suspicion of sodomy of a child under age 14 and rape of an unconscious person, the San Bernardino County jail log shows. Bibian has not been charged.
Rialto police arrested Bibian, but the Indio Police Department is investigating the case, according to the Riverside County Sheriff’s Department. An Indio police spokesman could not be reached for information on the circumstances of the allegations.
Bibian had not been charged, the Riverside County District Attorney’s Office said. Bibian is no longer in custody. He could not be reached for comment.
Bibian is an English teacher and the head boys cross country coach at Eisenhower. He has been employed by the Rialto Unified School District since 2016.
“Once we were notified of the allegations, he was placed on administrative leave,” Rialto Unified School District spokesperson Syeda Jafri said in an emailed statement. “The district is cooperating with law enforcement agencies in the investigation.”
Pulido encouraged parents to report anything suspicious and directed questions about Bibian to Indio police Lt. Andrew Leyva at 760-541-4598.
