Cardinal George Pell has been filmed by a member of the public on a stopover in Singapore, apparently on his way back to Australia.

Pell is due to face court in Melbourne later this month on historical sexual assault charges.

Victoria Police have alleged the charges involve multiple complainants.

A member of the public filmed a casually dressed Pell sitting outside an ice-cream shop before asking if he was innocent.

"I just called my mother and she wants to know if you are innocent," the bystander asks.

Pell replied: "Tell her that I am."

The senior Catholic figure has maintained his innocence and said he is looking forward to returning to Australia to clear his name.

Editor's note: On Tuesday April 7, 2020, the High Court in a unanimous decision upheld Cardinal Pell's appeal and quashed his convictions on all five charges.
