SIMMERING tension between rival bikie gangs exploded on the Gold Coast yesterday with the drive-by shooting of a tattoo parlour in the heart of Bandidos territory. Police fear the attack could be a push for territory by the Hells Angels as the outlaw gang seeks a toehold on the lucrative Glitter Strip. Less than 24 hours after police commissioner Bob Atkinson told the Bulletin that bikie gangs were "one of the greatest challenges to face law enforcement", the Bandido-protected Mermaid Beach tattoo shop was hit by at least four shots in the early hours of yesterday morning.  High-ranking police yesterday said it was "inevitable" that the violence that has plagued Sydney would eventually spill across the border. "We do not believe it is directly connected to the war between the Hells Angels and the Nomads that has been unfolding in New South Wales," said police. "But it is a similar style of attack. "We know the Hells Angels have been pushing to establish a chapter on the Gold Coast -- that push is coming from Sydney. "Tradelink Drive is not their most profitable chapter." While detectives have attempted to play down the shooting, police say there is "no doubt" it was intended as a warning. The Bandidos are the largest and one of the most secretive bikie gangs on the Gold Coast. The club has gained strength as its main rival -- the Finks -- have been severely weakened with so many senior members behind bars and Bandido territory stretches south from Broadbeach. Police said last month's Hells Angels National Run was intended as a direct message to all gangs on the Gold Coast. More than 200 patched gang members descended on Surfers Paradise for the run. "These clubs are so well organised, they do nothing without a reason," police said. "You can bet they had some purpose in coming to the Gold Coast. "They taunted the Finks and nothing happened, now the Bandidos tattoo shop is shot up in the same way the gym controlled by the Hells Angels was hit a few months ago. "You join the dots." The shop is owned by a senior member of the outlaw gang who has been a patched member of the Bandidos "for years", police say. In an exclusive interview with the Bulletin, Mr Atkinson said the danger of bikie gangs was "under-rated" by the community. "The outlaw motorcycle gangs nationally present one of the greatest challenges to police. "I think the degree of that challenge and the risk they present to our society is underrated." The Gold Coast has one of the highest populations of bikie gangs in the country. Mr Atkinson said he would not be surprised if the Hells Angels were not considering a move closer to the Glitter Strip. "They are businesses, they look for opportunity so that wouldn't be a surprise," he said. "They market themselves as a group of mature men who have a love and interest in motorbikes and they do that very cleverly. The reality is they are highly sophisticated, well organised criminal enterprises that pose a genuine risk to the community and many are well represented by the finest and best lawyers who they retain to represent them." South East Region Assistant Commissioner Graham Rynders said the gangs were constantly looking to expand. "One of things about OMCGs is they look for opportunity for criminal enterprise," Mr Rynders said. "Throughout Queensland, throughout the country, probably throughout the world they are looking to expand. It is obviously dictated to by territory, depending on who or what other groups exist in what areas."
