Many of those reports stemmed from the Secretariat's controversial investments, including the purchase of a London property for hundreds of millions of dollars.
Since October, investigators in Vatican City have conducted several raids on different Vatican departments in connection with the London property deal and connected investments. Investigators raided offices at the secretariat and the AIF, the Vatican's financial watchdog, seizing computers and phones and resulting in the suspension of several members of staff.
After those raids, investigators also raided the home and offices of Msgr. Alberto Perlasca, who worked closely with Becciu at the Secretariat of State.
In June, Vatican authorities arrested Italian businessman Gianluigi Torzi, who helped broker the final sale of the London building.
In July, Italian police served a search and seizure warrant on Raffaele Mincione, an associate of Torzi's, through whom the Vatican invested hundreds of millions of dollars. The warrant was issued at the request of Vatican prosecutors. Investigators took away cell phones and tablets for examination in relation to the case. Mincione has repeatedly denied any wrongdoing, and earlier this year filed a lawsuit against the Secretariat of State in a U.K. court, asking a judge to rule he acted in good faith in his dealings with the Vatican.
Iai's most recent communication on behalf of Cardinal Becciu, released Monday, announced that he had filed complaints on behalf of the Becciu family "for violation of the criminal provisions on slander and aggravated defamation and prohibition of disclosure of office and investigation secrets, [and] cases of corruptive malpractice."
Iai said that "the illegal leakage of confidential information and documents continuously disclosed by the media in a distorted and disparaging form" had "led to the committing of further crimes and the infringement of the rights of various interested parties."
Iai did not specify which media were the subject of his complaints, or to what authority he had submitted them.
