Veteran radio broadcaster Alan Jones has been arrested over indecent assault and sexual touching allegations spanning two decades.

Jones, 83, was arrested in Sydney on Monday morning before police performed a search on his luxurious Circular Quay unit.

Investigators are yet to confirm that any charges have been laid.

The arrest followed a months-long investigation into allegations aired in Nine newspapers that the talkback host had repeatedly used positions of power to prey on young men.

Those allegations included putting his hands down the pants of students while he was a teacher and indecently assaulting a number of young men throughout his influential broadcasting career.

Jones’ lawyer Mark O’Brien denied the allegations on his client’s behalf when they were first detailed in December 2023.

“Our client denies ever having indecently assaulted the persons referred to … and (the) suggestion that he has is scandalous, grossly offensive and seriously defamatory of him,” he said in a statement at the time.

NSW Police on Monday said an arrest had been made after a near-nine month investigation.

“In March 2024, State Crime Command’s Child Abuse Squad established Strike Force Bonnefin to investigate a number of alleged indecent assaults and sexual touching incidents between 2001 and 2019,” a statement said.

“Following extensive inquiries, about 7.45am strike force detectives executed a search warrant at a unit in Circular Quay where they arrested an 83-year-old man.”

Jones began broadcasting in 1985 after a failed political career and became a feared interviewer capable of grilling leaders while dominating the airwaves with his outspoken, conservative views.

He worked with Sydney radio station 2UE before joining rival 2GB, where he was a long-time ratings juggernaut.

His many controversies included suggesting former prime minister Julia Gillard’s father “died of shame” and encouraging former New Zealand leader Jacinda Ardern to be hit “with a few backhanders”.

Jones most recently broadcast via digital platform ADH TV, but he has not been on-air since November 2023, shortly before the indecent assault allegations were published.

He also coached the Australian national men’s rugby team between 1984 and 1988, with his tenure including a number of historic achievements for the side.

They included leading the Wallabies to a grand slam of wins on their British Isles tour in 1984 and coaching the side to Australia’s first Bledisloe Cup win in New Zealand in 39 years in 1986.
