SOUTH DAYTONA, Fla. -

A Volusia County teacher charged with making child pornography may have molested children at the school where he worked, according to officials.

Matthew Graziotti was a teacher and summer camp counselor at the Warner Christian Academy in South Daytona.

Initially, school officials told parents they did not think Graziotti harmed any students on campus, but now police and the FBI say they are investigating at least one case of suspected case of molestation at the school.

The Daytona News-Journal reports the incident happened during a sleepover of 13-year-olds at the end of a summer camp last year.

Graziotti was fired from Warner Christian and remains in jail without bond.
