Priests and teachers physically or sexually abused more than 500 boys at a Catholic choir school in Germany between 1945 and 1992, according to a report.
Allegations in Tuesday's report involving the Domspatzen choir at the Regensburg Cathedral Sparrows school were among a spate of revelations of abuse by Roman Catholic clergy in Germany that emerged in 2010.
Many of the 547 victims remembered their time at the school as "the worst time of their lives, marked by fear, violence and helplessness", said lawyer Ulrich Weber, who was commissioned two years ago by the diocese to probe the cases.
