Former Leto High School teacher arrested for 'inappropriate conduct' with student: HCSO

TAMPA - A former Tampa high school teacher has been arrested after he allegedly engaged in "inappropriate conduct" with a student on campus, according to the Hillsborough County Sheriff's Office.

An investigation into Gregory Sinadinos, 33, began earlier this week after a school resource deputy was told about "suspicious communication" between a teacher and a student. Detectives from the Special Victims Section immediately responded to the school.

They also confirmed that he had been a TV production teacher at Leto High School since August 2024.

What they're saying:

Sheriff Chad Chronister released a stern statement following the arrest, emphasizing the breach of trust between educators and the community.

"Parents trust that when they send their children to school, they are entering a safe environment focused on learning and growth," said Sheriff Chronister. "There is absolutely no excuse for an adult in a position of authority to engage in inappropriate conduct with a student. This arrest sends a clear message: anyone who exploits or attempts to exploit a child will be held accountable."
