(AP) - FILE -- In this Aug. 9 2008 file picture Georg Ratzinger, brother of Pope Benedict XVI, is seen during a ceremony in Bressanone, Italy. The Regensburg Diocese says a former member claims he was abused while singing with Germany's leading Roman Catholic boys choir that was led for 30 years by the brother of Pope Benedict XVI. The Diocese said in a statement Friday, March 5 2010, that one former member of the Regensburger Domspatzen claimed priests abused him in the early 1960s. The pope's brother, Georg Ratzinger, led the choir from 1964 to 1994. He told public radio Bayerischer Rundfunk on Friday he did not know of any abuse cases at the choir.

(AP) - FILE - Georg Ratzinger, brother of Pope Benedict XVI, gives interviews in Regensburg, southern Germany, in this April 20, 2005 file photo. Scandals over sexual abuse by Catholic clergy of minors and cover-ups by church hierarchy have exploded in recent months in countries including Ireland, Germany and the Netherlands. The German abuse allegations are particularly sensitive because Germany is the homeland of Pope Benedict XVI and because the scandals involve a prestigious choir that was led by the pope's brother, Georg. Asked in an interview Tuesday March 9, 2010 whether he knew of the allegations when he took over as head of the choir in 1964, Ratzinger insisted he was not aware of the problem. 'These things were never discussed,' Ratzinger told Tuesday's Passauer Neue Presse German daily. (AP Photo/Uwe Lein,File)
