The Vatican confirmed on Saturday, May 26, 2012, that the Pope's butler has been arrested in its embarrassing leaks scandal, adding a Hollywood twist to a sordid tale of power struggles, intrigue and corruption in the highest levels of Catholic Church governance. The Vatican had already warned of legal action against the author, Italian journalist Gianluigi Nuzzi, after he broadcast letters in January from the former No. 2 Vatican administrator to the Pope in which he begged not to be transferred for having exposed alleged corruption that cost the Holy See millions of euros in higher contract prices.
