"Harry Potter was a giant of Australian journalism and devoted more than 50 years of his life to the profession," Network Ten CEO Hamish McLennan said in a statement on Friday.
"He defined crime reporting for a generation and his legacy remains a major part of the newsroom at Ten.
"Harry was in the front row of Australian police and crime reporting for the past half century and became a household name, bringing Australia's criminal underworld and all of its colourful characters into the lounge rooms of Ten's viewers."
