Police monitoring Hells Angels NT event HELLS Angels bikies who are converging on Darwin for the annual run can expect to be closely watched, police say. Northern Territory police on Friday said they had been monitoring the arrival of up to 200 Hell's Angels motorcycle club members in the city over the past few days and would continue to keep an eye on them over the weekend. The bikies' annual run on Saturday will be the first real test of the territory's temporary liquor licensing laws, which prohibit licensed venues serving anyone wearing colours or insignia related to a known outlaw motorcycle gang (OMCG). Police say the event will cause some delays on roads as large groups of motorcyclists ride around the city. "Outlaw motorcycle gangs have a history of serious criminal activity and the NT Police make no excuses for observing the movements of these members," Commander Wayne Harris said in a statement. This is a preventative exercise aimed directly at letting this OMCG know that any criminal or anti-social behaviour will not be tolerated.
