The Comanchero expansion into Western Australia was delayed by the 2010 arrest of Steve Milenkovski who was about to be patched as the Perth’s Chapter president when he was arrested in the culmination of Operation Baystone.[18] Operation Baystone resulted in Milenkovski, Yavuz Ozan, Hao Bi, and Mark Vick Kitos being charged with various drug offences. The operation seized 7.5 kilograms of methylamphetamine imported into Western Australia from New South Wales.[19]
