Today Corey Barker described the events that took place in the video, saying another young man was trying to steal his girlfriend.
This event, a previous conviction for assaulting a police officer and Mr Barker's use of testosterone in 2010 formed the basis for most of the questions.
Corey Barker was asked whether he thought he started the fight between him and the police in the back room.
Mr Eurell claimed when Mr Corey turned his shoulder, he intended to set upon one of the officers, and that caused the sequence of events that followed.
Constable Mewings' lawyer asked Corey Barker "Do you agree that you started this altercation by turning on Senior Constable Hill?". "No. Not at all," Corey replied.
Brett Eurell also said that at the time of the incident Corey Barker was a violent, drunken and abusive man.
The phone that Corey Barker tried to use to film an alleged police assault on a young woman was also raised.
Corey Barker said he thought the police wanted the mobile because they presumed it contained a video of the incident.
While he was in the lock-up, an officer walked over to him with what appears to be a mobile phone in his hand, he said. "The officer said 'Tell me the f****ing code or I'll f****ing smash it'," he added.
Tomorrow the police officers involved are expected to give evidence. .
