According to Scarlett, the 20-minute pursuit by a film crew ended only when, hysterical and disorientated, she slammed into a police car that was dispatched after she made a triple-0 call, the Daily Telegraph reports.
The reality star retracted her statement later that day, declining to proceed with an assault complaint.
Accounts of what happened differ, but the police statement alleges Cooper was grabbed by the male producer, dragged inside a function centre and prevented from leaving.
The blonde admitted in her statement to smashing the producer’s mobile phone after discovering she was being filmed in a distressed state.
Bruise marks shown to officers turned out to be make-up smudges.
A Nine spokeswoman said there had been an incident on set that offended Cooper and prompted her to try to leave.
The spokeswoman also denied any altercation with a producer.
