Robert Charles Piraino, 37, a Nashville fencing coach facing charges of sex crimes involving one of his minor students, has been re-arrested on an indictment of sexual battery of another student.

The then 17-year-old male student says Piraino, the owner and head coach of Music City Fencing, inappropriately touched him during a private lesson.

Piraino was arrested in August on two counts of inducing sexual activity by a minor. He is accused of paying a 15-year-old female student to send him explicit photos and videos of herself.

Upon further investigation, he was indicted by a grand jury on 108 counts of alleged sex crimes involving a minor.

In testimony to a General Sessions court last fall, the juvenile victim said Piraino would work her harder in lessons as punishment if she did not send him the photos or videos he wanted.

Piraino was out on bail with a GPS ankle bracelet when he was arrested Wednesday on the new charge of sexual battery by an authority figure.

His bail conditions also included no contact with the victim or her family, no contact with minors, no access to pornography and no leaving the county without permission.

Parents whose children took lessons from Piraino at Music City Fencing Club are encouraged to talk with their kids and report any concerns to the Metro Nashville Police Department’s Youth Services Division at 615-862-7417. Detective Brian Zullo is leading this investigation.
