In August 2017, the U.S. State Department notified the Holy See of a possible violation of laws relating to child pornography images by a member of the diplomatic corps of the Holy See accredited to Washington.

A few weeks later, the United States requested that Capella’s diplomatic immunity be waived to open the way for possible prosecution there, but the Vatican refused.

After Capella was recalled to Rome, police in Windsor, Canada, said they had issued an arrest warrant for him on suspicion of possessing and distributing child pornography on the internet while visiting a church in Canada.

The trial was adjourned until Saturday.
