I don’t know anything beyond the news reports that began trickling out yesterday:
The head of the Vatican bank has formally been placed under investigation in an inquiry into a suspected violation of Italy’s money-laundering laws, judicial sources said today. At the same time, a judge in Rome ordered a freeze on €23m (£19.5m) held in an account opened by the Vatican bank, the Institute for the Works of Religion (IOR), at another financial institution in the Italian capital. It was thought to be the first time such action had been authorised against the IOR in Italy. (UK Guardian)
The Vatican is standing behind the two men under investigation:
The Vatican expressed its full confidence in Mr Gotti Tedeschi. In a statement it expressed surprise at the investigation and said it remained committed to financial transparency. (Financial Times)
This morning’s Vatican Informative Service bulletin echoed the above. This isn’t the first time the people charged with handling the Vatican’s finances have come under suspicion.
