A move by Hells Angels bikies into the territory of the Comancheros sparked a turf war Bikie wars artwork Source: Supplied IT was a brazen and cold-blooded slaying that came with a grisly warning from a rival bikie gang: "Get off our turf." Police are on high alert for retaliatory violence in Sydney's south following the murder of Hells Angels associate Tyrone Lee Slemnik, 37, gunned down outside his Eastlakes flat on Monday night. They believe Slemnik's drive-by shooting death was a message from the Comanchero east chapter to Hells Angels east city chapter members, such as Suat Sarmisakliglu, who lives in the same unit complex, to leave the area. Crime figure shot dead in Sydney While the Comanchero's control the lucrative eastern beaches drug trade, violence has escalated in recent months as the Hells Angels try to widen their footholds. Shootings are no longer restricted to Sydney's west as outlawed bikie gangs continue to grow, spreading their deadly tentacles to all parts of the city. But Eastlakes, nestled along-side some of the country's most prestigious golf courses, The Lakes and The Australian, is unlikely bikie territory. The crime scene in Easlakes. Picture: Hearne Bill Source: The Sunday Telegraph The Botany suburb, population 6920, is a mix of public housing, university graduates and a growing Islamic community where Bangladeshis and Indonesians have overtaken Greeks and Turks as the dominant ethnic groups. But the Comanchero had viewed these streets as part of their territory until Sarmisakliglu moved into a unit block in Universal St. To neighbours, an increased exposure of heavily tattooed types in hooded jumpers spelt trouble. Residents of George St, near the rear entrance to the unit block where the shooting occurred, had noticed an increase of heavily tattooed men wearing hooded jumpers over the past few weeks and months "guarding" the unit carpark. Slemnik, 37, a father of three, was one of the "tough" guys hanging around by the carpark as a rite-of-passage to earn Hells Angels "colours," when he was killed in the drive-by shooting at 10pm on Monday.

Neighbour Louise Caguicla said a black car was parked in the driveway entrance in the hours before the shooting forcing her husband to park on the street. Police use metal detectors to search the scene where a bikie gang member was shot and killed at George St, Eastlakes in Sydney. Another resident said he saw close to a dozen men outside the complex, when usually there were a handful on "guard duty" or sitting in cars, on Monday afternoon but they all left in cars before returning several hours later. The Hells Angels began moving east after their Chinatown chapter was all-but dismantled when one of its members was charged for supplying cocaine and amphetamines. They have yet to establish a clubhouse but use an Eastlakes reserve near Sarmisakliglu's unit to meet and are regulars at the Lakes Hotel up the road as well as a local chicken shop and hairdresser. Sarmisakliglu is well-known to police. He, and four other Hells Angels, were charged over the alleged extortion of Burwood luxury car dealer Terry Mullens in 2011 but the charges were dropped last year when Mullens refused to testify after his business was firebombed. In what may have been a portent of things to come, two Hells Angels prospects, Ashoor Khaie and Tony Raniga, were charged earlier this month after they were stopped in a taxi in Campbelltown with a loaded SKS assault rifle. They were refused bail and will appear at Central Local Court on Tuesday. Gang squad commander Superintendent Arthur Katsogiannis said police were ready for any reprisals. "We believe this attack was targeted and we want to assure the community we are providing a significant response to prevent any future retaliation," he said. Our message is we'll be out with a strong presence in unison with local commands to make sure the community is safe and let those individuals know we will not allow them to get away with any criminal acts. Former Kings Cross detective-turned crime author Duncan McNab said the Hells Angels and Comanchero would do anything to control the drug trade and regard the eastern suburbs as the "jewel in the crown." He said the Hells Angels may be capitalising on internal feuds within the Comanchero and moving into a rival's territory, by a number of gang members living in the area, a familiar pattern for the gang. Mr McNab said it was extremely likely the Comanchero were responsible for Monday's shooting but nothing was certain in the vicious bikie underworld. He said retaliation would be high on the Hells Angels' list and the "gloves had come off" due to a mix of "greed, testosterone and politics." "They want it all," he said. Police said they were investigating a link between the fatal shootings at Eastlakes and Abbotsbury on Friday and a South Granville house that was peppered with bullets in a drive-by shooting yesterday.
