Chaouqui was released by Vatican prosecutor Roberto Zannotti on Monday after agreeing to work with investigators.
Hand-picked by the Pope, Chaouqui’s role in the economic commission was heavily scrutinized in 2013, when it was revealed that she had previously been highly critical of the Vatican on Twitter.
Vallejo Balda, who served on a special commission to advise Pope Francis on economic reform, currently remains imprisoned.
Over the weekend, it was reported that the Vatican was looking into an attempted theft of a laptop belonging to Libero Milone, who now heads their finance office.
The Vatican is also angrily denouncing two new books set to be released this week that are said to include information from hackers on scandals within the Vatican’s finances.
“As far as the books announced for the coming days go, it is clear that this time too, just as in the past, they are the fruit of a serious betrayal of the pope’s trust,” a statement from the Vatican reads.
In 2012, there were also a series of leaks that alleged major fraud within the Vatican, engineered by Pope Benedict XVI’s butler.
The butler, Paolo Gabriele, was sentenced to 18-months in prison over the theft of private memos, but was pardoned by the Pope.
Despite the pardon, Gabriele was banished from the Vatican permanently.
