Bouncers should be put on notice after Crown incident, court hears CROWN bouncers who assaulted and falsely detained two patrons at the casino should be jailed and the security industry put on notice that thuggish behaviour won't be tolerated, a court has heard. Prosecutor Andrew Tinney, SC, today called for jail terms for three guards involved in an attack on two friends of Anthony Dunning, who died four days after tangling with security staff on July 3, 2011. Olivia Ferguson and Matthew Anderson had been drinking with Mr Dunning before being assaulted by staff when a scuffle broke out, sparked when an intoxicated Mr Dunning was asked to leave the venue. The couple were following Mr Dunning out when Ms Ferguson slapped bouncer Quoc Hai Tran in the face. She was slammed to the ground and restrained her in a painful "shut-down" hold. Mr Anderson was also slammed to the floor and restrained after turning to see his partner being held down. A Supreme Court jury found Mr Tran, 34, guilty of assaulting and intentionally causing injury to Ms Ferguson while colleague Jacques Tony Fucile, 31, was found guilty of intentionally causing injury to Mr Anderson. Both men, and a third bouncer, Nicholas Vladamir Levchenko, 27, were found guilty of unlawfully detaining the pair. Mr Tinney said the men had "completely failed, all three of them, to abide by their duty" and said the imposition of a jail sentence would not be beyond the court's power. He said a strong message had to be sent to security staff that "such conduct in breach of their duties will be met with strong condemnation from our courts," he said. Mr Tinney said the men were employed to safeguard the welfare of patrons, not attack them. He said while their victims were vulnerable and powerless, the bouncers were part of a very powerful contingent as employees of Crown Casino's security arm. While lawyer's for the men had argued they had acted in self defence in accordance with Crown training procedures, Mr Tinney said the thuggish attack had been unnecessarily sparked by anger and aggression. "It doesn't say very much for the textbook, if this was textbook," he said. Lawyers for the men argued yesterday they should be fined and escape conviction. They argued the men had been subjected to a lengthy criminal proceeding and had been humiliated by media attention. They would also not be able to work in the security industry for at least five years, and 10 years if they received conviction, the court heard. In November, another Supreme Court jury found bouncers Matthew Scott Lawson, 27, and Cameron Paul Sanderson, 40, not guilty of manslaughter, and Benjamin Michael Vigo, 24, not guilty of assault over the incident with Mr Dunning. Tran, Fucile and Levchenko were bailed for a sentence hearing on June 14.
