Roman Catholic leaders in Austria called an emergency meeting today after officials discovered a vast cache of photos and videos allegedly depicting young priests having sex at a seminary.

About 40,000 photographs and an undisclosed number of films, including child pornography, were downloaded on computers at the seminary in St Poelten, about 50 miles west of Vienna, the respected news magazine Profil reported.

“Anything that has to do with homosexuality or pornography has no place at a seminary for priests,” it said.

Church officials discovered the material on a computer at the seminary, Profil said. It published several images purportedly showing young priests and their instructors kissing and fondling each other and engaging in orgies and sex games.

The child porn came mostly from web sites based in Poland, the magazine said.

Bishop Kurt Krenn, a conservative churchman who oversees the St Poelten Diocese, told Austrian television he had seen photos of seminary leaders in sexual situations with students. Krenn, however, dismissed the photos as “silly pranks” that “had nothing to do with homosexuality”.

A group of St. Poelten Diocese officials planned to ask the Vatican to remove Krenn as bishop, Austrian radio reported.

Vatican spokesman Ciro Benedettini told the Austria Press Agency that the Holy See had no comment.

Krenn, 68, issued a statement calling the accusations groundless while conceding that he “may have made some wrong personnel decisions” at the seminary.
