Bayeh admits assaulting Edelsten's ex

Former Kings Cross identity Bill Bayeh made a threat involving a sex toy to Geoffrey Edelsten's ex-wife during an ugly verbal spat, court documents reveal.

Bayeh pleaded guilty on Thursday in the Downing Centre Local Court to one count of common assault over the February 2015 incident, allowing the full facts in the case to be revealed for the first time.

The argument erupted after intensive care nurse Leanne Nesbitt passed Bayeh on her way to work at St Vincent's Hospital at about 6.40pm that Sunday.

Ms Nesbitt said nothing as Bayeh, now 57, greeted her from his outdoor table at the Five Boroughs coffee shop on Darlinghurst Road.

But she then stopped and turned to confront him about comments he'd made some weeks earlier, sparking an argument that was recorded on her phone.

"Never speak to me on the street. You need to be in jail," Ms Nesbitt said, according to a NSW Police statement of facts.

"They should never have let you out, you're a criminal."

Bayeh responded.

"You need a vibrator up your arse," he said.

"You've got a tape going, haven't ya?"

Bayeh then jumped from his seat, according to the facts presented at the court.

"I'm going to shove a dildo up your arse," he allegedly said.

Ms Nesbitt feared for her safety and called police.

In a recorded interview, Bayeh admitted to a confrontation but denied pushing her or saying anything about a vibrator or dildo.

His sentencing was adjourned until next month so psychiatric evidence can be gathered.

Bayeh will be sentenced at the same time for hindering police in a separate incident three days before the February 2015 assault.

On that occasion, Bayeh was accused of tearing up a handwritten "drug code" when he was searched by police outside the same coffee shop.

He pleaded guilty to the hindrance charge earlier this month, while prosecutors dropped a second charge of resisting police.

Bayeh will return to court on April 21.

Ms Nesbitt was married to Mr Edelsten for four years during the 1980s when the colourful businessman owned the Sydney Swans.
