59-year-old Fernando Rivas appeared in a South Carolina federal court yesterday — where he pled “not guilty,” according to the Charleston Post & Courier.

Rivas was arrested back in April — after FBI agents raided the composer’s home and, according to court docs, the feds claim they discovered a collection of photographs … depicting a 4-year-old girl naked and “restrained in handcuffs and other bondage-type devices.”

According to the report, cops say Rivas — who also taught music at a local Charleston school — admitted to officers that he took the pictures of the little girl and emailed them to two other sickos.

Rivas remains on house arrest after posting $300,000 bail.
