The alleged incident took place at Sydney's Clovelly Hotel on February 3, after Elordi was approached by Fox, who works on KIIS FM's The Kyle and Jackie O Show.
"Officers attached to Eastern Beaches Police Area Command are investigating after a man was allegedly assaulted outside a hotel in Sydney’s Eastern Suburbs," NSW Police said in a statement.
"Police were told about 3.30pm on Saturday, 3 February, 2024, a 32-year-old man was allegedly assaulted by a 26-year-old man. The man did not sustain any injuries."
On Monday, Kyle and Jackie O played the audio Fox recorded, which shows Fox telling Elordi that Jackie O would like his bathwater as a birthday gift — referencing a much-discussed scene from film Saltburn.
"He kind of gets up in my face," Fox recalled on-air. "I could've kissed him he was that close.
"So I'm backed against this wall, he's right in my face and his two boys are now on either side of me... I'm feeling quite intimidated."
Fox said he apologised to Elordi, who "flipped" when Fox also said he would not delete the footage he had taken.
"The way they're surrounding me, I'm thinking something's going to happen here. Someone's going to jump me or something. So I say, 'No, I'm not deleting that,'" Fox stated. "I refuse to because I feel uncomfortable right now, and this is the only evidence. And then Jacob kind of just flips, and he kind of pushes me against the wall, and his hands are on my throat."
