A teacher accused of possibly directing student assaults at AB Miller High School in Fontana was arrested on suspicion of child cruelty that could have caused injury or death, officials said.
Emmanuel Del Rosa, 27, was booked into the San Bernardino County Jail. He was released after posting bail.
Jail booking records online gave no information about his next court appearance.
Police believe Del Rosa -- he also goes by the name De La Rosa -- possibly "directed students to assault another student due to behavioral issues.”
Four students also were arrested in connection with an assault that left a student with minor injuries, police said Sunday.
The incident happened during summer-school which began May 31, police said. The case came to light on Friday after Fontana Unified School District police notified the Fontana Police Department about a possible hazing incident.
"Our detectives interviewed several students in that classroom and subsequently located three victims of a hazing, assault-type incident," said Sgt. Robert Morris.
Four students participated in the assaults, police said in a news release without elaborating, citing the ongoing investigation. In addition to the student who was injured, two other students were victimized, police said.
One of the students, Fernando Manuel Salgado, 18, was booked into the San Bernardino County Jail on suspicion of assault, child cruelty and attempted penetration by foreign object, according to booking records online. He’s expected in a Fontana courtroom on Tuesday. His bail was set at $100,000.
Clarification: An earlier version of this story reported that the suspect was charged with attempted sodomy. The story has been changed to reflect the official charge: "attempted penetration by foreign object."
