Six members of the Mongols Outlaw Motorcycle Gang have been charged over an alleged fight at a pub in Secret Harbour.
It's alleged a group of 12 Mongols approached three Mongrel Mob OMCG members at the Whistling Kite around 9.30pm on August 26.
A verbal altercation allegedly happened between the two groups before a violent brawl broke out in front of a number of innocent patrons.
Extensive inquiries by Gang Crime Squad Detectives led to a number of search warrants being executed on September 1.
As a result, six Mongol members have been arrested and charged with various offences including fighting in public causing fear and displaying insignia of an identified organisation in a public place.
They are due to appear in court later this month.
Inquiries are ongoing into the alleged incident and further charges may follow.
Each person involved will also be handed a barring notice under the Liquor Control Act.
