A Canberran member of the Finks bikie gang was arrested at the Sydney casino on Saturday, after allegedly threatening to assault a police officer.
Police were called to the Star casino in Pyrmont early on Saturday. Casino security had raised concerns members of two bikie gangs, the Comancheros and the Finks, were at the venue.
Officers attached to Strike Force Raptor - a NSW Police squad established in 2009 to target outlaw motorcycle gangs - arrived at the scene and spoke with four Finks bikies.
They allege one of the bikies, a 27-year-old from Canberra, threatened to assault a constable.
He was arrested and charged with intimidating police and offensive conduct.
The Canberra man has been bailed, and will appear at Downing Centre Local Court on February 22.
Three Comancheros bikies were also spoken to, and one allegedly used offensive language.
The 31-year-old is expected to be brought before the court at a later date for offensive language.
