A work Christmas party ended in alleged violence, with police saying a security guard was bitten on the arm by an unruly pub patron while his boss obstructed them during their arrest. Police say about 8.30pm on Friday, security working at the Foreshore Hangout asked a man to leave the premises after he was accused of causing a disturbance. Officer-in-charge Sen Sgt Chris Martin alleged the man shoved security with two hands and he was subsequently restrained by several security guards until police arrived. “During the scuffle the victim was bitten by the suspect on his left forearm,” he said. Sen. Sgt Martin said during the arrest, the man allegedly tried to physically fight officers while he was being handcuffed. He alleges the man’s 42-year-old boss intervened and obstructed police. “The suspect’s boss intervened and physically obstructed officers from their duty, grabbing a police officer by the vest,” he said. “The suspect’s boss was taken to the ground and arrested.” Sen. Sgt Martin said the arrest was another example of poor behaviour in a licensed premises and would investigate the venue’s performance of the Responsible Service of Alcohol. “Police will always adopt a zero tolerance approach to anti-social behaviour, especially in licensed premises,” he said. “Police will undertake a full and thorough investigation in order to identify the amount of alcohol consumed on the premises and how staff applied their responsibility to responsible sale of alcohol. The 42-year-old man from Geraldton was summoned to court charged with obstructing police. “There’s a time and place to speak to police and respectfully intervene,” Sen. Sgt Martin said. Charges against the other man are yet to be finalised.
