Cardinal George Pell has vehemently rejected allegations he sexually abused minors and called for an inquiry into what he claims is a Victoria Police media leak that he has been under investigation for more than a year.

The Herald Sun claims Victoria Police Sano taskforce has a collection of documents alleging Cardinal Pell committed "multiple offences" while he was a priest in Ballarat and also the Archbishop of Melbourne.

A statement issued from Cardinal Pell's office states "the allegations are without foundation and utterly false".

Victoria Police say they are investigating a number of historical sexual abuse accusations and are looking at evidence given to the Royal Commission.

In the statement, the Catholic Church says the timing of the leaks to the Herald Sun is "clearly designed to do maximum damage to the Cardinal and the Catholic Church and undermine the work of the Royal Commission".

The claims have not been raised with Cardinal Pell by police, but have instead come to his attention via media reports, it states.

The statement refers to the "Phillip Island allegations" which it says are "outrageous" and "clearly designed to embarrass the Cardinal", despite being available on public record for nearly 15 years.

"The Southwell Report which exonerated Cardinal Pell has been in the public domain since 2002," it states.

"The Victorian police have taken no steps in all of that time to pursue the false allegations made ... [and] have never sought to interview him in relation to any allegations of child sexual abuse."

The statement calls for those Victoria Police members who leaked the confidential information to media outlets to be scrutinised in a public inquiry.

Now the Vatican's finance chief, Cardinal Pell is to give evidence to the sex abuse royal commission via video link from Rome from February 29.
