The Vatican announced the arrest of a diplomat with ties to Windsor Saturday.
Monsignor Carlo Capella was recalled from the US by the Vatican Secretary of State last year after a three-nation investigation tied him to child pornography.
Windsor police allege Capella uploaded child porn from a social networking site while visiting a place of worship in December of 2016.
The US State Department reported a "possible violation of laws relating to child pornography images" by a Vatican diplomat in Washington in August of 2017.
