TAMPA, Fla. – Parents of students at a Florida middle school are livid after learning a substitute teacher was accused of masturbating during class and they weren’t notified about the incident.

More than a dozen parents told WFTS they’re outraged after learning numerous students likely witnessed a substitute teacher at Shields Middle School masturbating behind his desk during class time in February and they were never informed by school officials.

One student in the class recorded video of the teacher that appeared to back up the accusations, showing the teacher moving behind the desk. Numerous students told Hillsborough County deputies they witnessed the teacher masturbating, while two said they saw his “belt unbuckled and his zipper down.”

Others told authorities they saw naked women on the teacher’s cell phone and “his erection was also visible,” according to the news site.

“The more we started paying attention the more people we started letting know about it,” a student told WFTS. “And the more we started realizing what he was doing.”

Harrison Peters, the district’s chief of schools, attempted to downplay the incident by labeling it “an accusation of an adult” and alleged officials removed the teacher from the classroom immediately and contacted sheriff’s officials and parents when notified of the accusations.

But the police report detailing the investigation told another story.

The report alleges a parent notified the sheriff’s department days after the incident, and more than a dozen parents who spoke with WFTS said they knew nothing about the controversy until contacted by the news site.

The parent who contacted the sheriff’s department told WFTS the school resource officer – a Hillsborough County deputy – had “no idea” about the incident when she contacted him.

“I said this man needs to be arrested, something needs to happen,” the woman, who was not identified, told the news site. “And he had no idea what I as talking about.”

“I’m upset because the school didn’t notify me,” said different parent with a child in the class.

“It’s just frustrating because nobody is listening,” another parent said.

Regardless, Peters insisted to WFTS that school officials notified all parents and “the majority of the parents were very supportive, they understood.”

Peters provided the news site with hand written notes from a school administrator with a timeline of events, but WFTS pointed out that “the notes are not time stamped, dated, or signed” and school officials could not authenticate the document.

Parents, meanwhile, are calling out Peters for calling them liars.

“I know that I never received any letter, any phone call, anything outside of me contacting the school,” one parent said.

Another father told WFTS: “I contacted the schools and asked about the incident and no one ever got back to me.”

Hillsborough County Schools banned the teacher from substituting in any district schools ever again, but deputies said there’s currently not enough evidence to bring criminal charges against him.
