The man was called Victim 6 in court papers. He sued Tuesday in federal court in Philadelphia, claiming Jerry Sandusky's behavior was "ratified" by The Second Mile charity and Penn State.

He's seeking at least $75,000 in damages.

Jerry 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. Messages for a Second Mile official and Jerry Sandusky's civil lawyers haven't been returned.

Victim 6 testified Jerry 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.
