At least 547 members of a renowned Catholic boys' choir in south western Germany were physically or sexually abused, a new report has found. The incidents took place at the Domspatzen choir in Regensburg between 1945 and 1992. The choir was run by Emeritus Pope Benedict XVI's elder brother Rev Georg Ratzinger between 1964 and 1994. The report concluded: "The whole system of education was oriented toward top musical achievements and the choir's success. "Alongside individual motives, institutional motives - namely, breaking the will of the children with the aim of maximum discipline and dedication - formed the basis for violence."
