EBENSBURG, Pa. (AP) — A former house parent at a Pennsylvania Catholic school has been jailed on charges that he sexually assaulted two Chinese international students he supervised.

Twenty-eight-year-old John Bowman Thornberry, of Mills River, North Carolina, was arrested last week is being held in Cambria County in lieu of $250,000 bail pending a preliminary hearing next week.

Thornberry was removed in February from his job overseeing Chinese international students at Bishop Carroll High School in Ebensburg, Pennsylvania.

One student said Thornberry took him to an area with no surveillance cameras and fondled him. Another boy said he fought off a molestation attempt. Officials are trying to locate at least one other possible victim.

Thornberry, who was hired in August 2014, declined comment last month. His attorney didn’t immediately return a call seeking comment.
