Authorities say they found child pornography on Bradley Ratcliff's home computer, though they want to clarify there is no evidence that students at the school here were victimized.
Ratcliff, 53, is accused of distribution and possession of child pornography after the Los Angeles Police Department searched his home and found evidence on the computer.
Authorities say it was a tip to the National Center for Missing and Exploited Children that led investigators to Ratcliff, a former varsity football coach.
"We were informed by the LAPD that this was an incident that took place off campus and that he was arrested at his residence for a situation that is unrelated to this campus," said Jose Iniguez, the principal at the high school.
Iniguez says Ratcliff was placed on administrative leave pending the outcome of the investigation and that the school informed parents of Ratcliff's arrest last week via pre-recorded phone messages.
Some parents on Thursday didn't seem to know anything about the situation and others expressed concerned.
Juanita Lacon said she was worried when she heard the news because her son has autism and is especially vulnerable.
Students also said they were concerned.
"Everyone is surprised and shocked because they don't believe it," said student Vanessa Castor. "We didn't know him well enough to say whether he did it or not."
Ratcliff was released on $20,000 bail following his Feb. 2 arrest and was expected back in court Feb. 25.
While students struggled to understand the charges, investigators are asking any possible victims to come forward.
Anyone with information about Ratcliff was asked to call (877) LAPD-247.
