Australian authorities are investigating a letter circulated on social media to see whether it was written by disgraced Cardinal George Pell, which would be in violation of prison rules.
Pell is the highest-ranking Catholic cleric to be found guilty of child sex abuse.
The 78-year-old, who was Pope Francis’s finance chief and one of his closest advisers, was convicted last December on one charge of sexual penetration of a child and four charges of committing an indecent act with or in the presence of a child.
Authorities are investigating whether the letter, dated August 1 and posted on Twitter, breaches rules forbidding prisoners from posting on social media or using the internet, or asking others to post on their behalf.
The letter was posted on Friday night on a Twitter account called Cardinal George Pell Supporters.
A spokeswoman from the Department of Justice of Victoria state, where Pell is in prison, said the letter was being investigated.
“(The department) will thoroughly investigate this social media activity,” the spokeswoman said. “Any prisoner found to be contravening prison regulations faces disciplinary action.”
