VATICAN CITY (AP) — A scandal over alleged sexual molestation and abuse at the Vatican’s youth seminary is growing, with more former papal altar boys alleging inappropriate behavior by priests inside the Vatican walls.

Le Iene, an Italian investigative television program, plans to air the new allegations Sunday; the show provided the broadcast to The Associated Press ahead of time.

The Vatican announced in September that its criminal prosecutor was seeking to indict a former senior seminarian and the then-rector of the St. Pius X seminary on sexual abuse charges.

The announcement came two years after Le Iene first featured former seminarians who alleged that the senior seminarian, now a priest, had molested teen-age boys who lived inside the Vatican and served as altar boys at papal Masses in St. Peter’s Basilica.
