WEST MILTON, Ohio -- Investigators in Miami County said the assistant band director of Milton-Union High School has been indicted on another charge of sexual battery.

The second charge comes less than month after a first charge of sexual battery was filed against Anthony Spahr.

Spahr, 28, was indicted on Friday on the second charge, involving a 16-year-old female at Milton-Union High School.

The allegations against Spahr were recently brought to the attention of authorities.

Superintendent Ginny Rammel said that Spahr had just begun his third year at the school. She said that on Oct. 5, the school received an anonymous tip that Spahr was involved in inappropriate behavior.

Rammel said she is very angry and upset about what has happened.

Capt. Dave Duchek said that during the first investigation, they found out about a possible second victim, and they are looking into that.

School officials said after conducting an internal investigation, Spahr was immediately dismissed.

Deputies in Miami County issued an arrest warrant for Spahr and he was taken into custody on Tuesday at his home in Troy.

He remains in the Miami County Jail.
