Papal investigation is ongoing into documents found in Paolo Gabriele's Vatican apartment, which he shared with his family. Investigators are working to determine how the documents reached the media. Gabriele, 46, remains in custody in a "secure room."
A Vatican source told the Financial Times more arrests likely will follow, as investigators do not believe Gabriele acted alone.
The massive leak, dubbed "Vatileaks," includes correspondence from Archbishop Carlo Maria Vigano, papal nuncio to Washington, that alleges corruption and financial mismanagement within the city state.
Meanwhile, more light was shed on last week's dismissal of Ettore Gotti Tedeschi, head of the Vatican bank. A memorandum from a four-person "board of superintendence" was released to the media citing nine reasons for Tedeschi's termination, including "failure to carry out basic duties incumbent upon the president to perform" and "the dissemination of documents last known to be in the president's possession."
The Vatican bank is also under investigation by Italian authorities for suspected money laundering, but the board's memorandum made no mention of the investigation as it pertains to Tedeschi.
