HARRISBURG, Pa. (AP) — A young man who testified at the child sex abuse trial of former Penn State assistant football coach Jerry Sandusky last summer is suing him, his charity and the university.

The man was called Victim 6 in court papers. He sued Tuesday in federal court in Philadelphia, claiming Sandusky’s behavior was “ratified” by The Second Mile charity and Penn State. He’s seeking at least $75,000 in damages.

Sandusky was convicted of abusing Victim 6 and nine other boys but maintains his innocence. He’s serving a lengthy prison term.

Penn State has declined to comment. The Second Mile says it will respond “through the legal process.”

Messages for Sandusky’s civil lawyers haven’t been returned.

Victim 6 testified Sandusky called himself “the Tickle Monster” and grabbed him inside a university shower in 1998. His mother’s complaint triggered a police investigation but no charges.
