A former admissions officer at an elite prep school in New Hampshire has turned himself in to face allegations that he sexually assaulted a teenager decades ago.

Arthur Peekel is accused of assaulting Lawrence Jenkens when Jenkens visited Phillips Exeter Academy in 1973. Peekel left the school soon afterward and went on to teach in Illinois, where he was named teacher of the year in 1992.

Peekel was free Friday on $25,000 bail. His arraignment on sexual assault charges was set for July 5. He didn't immediately respond to messages left for comment.

Peekel is the third Exeter staff member accused of sexual misconduct at the school.

The Associated Press generally doesn't name victims of alleged sex abuse but Jenkens said he wanted to discuss his case publicly.
