A man who was arrested at the Australian Open has been released pending further inquiry, as police investigate assaults on staff at the event.

Earlier on Wednesday, Victoria Police alleged a woman had been sexually assaulted at Rod Laver Arena just before midnight on Tuesday.

However, police have since changed their statement and no longer believe the sexual assault took place.

“Our information on the incidents at the tennis has changed,” a police spokesman said.

Reports of “assaults on staff members” at the venue are still being investigated.

A 37-year-old man was arrested and has been released pending further enquiries and the investigation is ongoing.
