The New Boys has been undercutting other dealers, and targeted outlaw bikies, the Hell's Angels, in a series of drive-by shootings in August.The New Boys emerged in the northern suburbs about four years ago and once congregated at pubs around Elizabeth and Smithfield. They use Hindley St as their base, as well as the Norwood entertainment strips, including The Parade, where they sell drugs. The gang has two "chapters" and is extensively involved in selling drugs, including ecstasy tablets and methamphetamine, and street fights, usually using knives.The group said to be headed by a city tattooist, the target of the bungled bomb attack who lashed out at cameramen yesterday when he returned to his home, metres from the crime scene.It was two hours before sunrise on Thursday when Enfield shook with the force of the home-made bomb, ripping apart a hire car and killing two men on Truscott Rd.Convicted drug runner Vahe Hacopian, 31, of Munno Para West, and a 23-year-old Walkley Heights Hell's Angels associate, made it within metres of their suspected target when the explosives accidentally detonated.Their target, a tattooist and New Boys drug dealer, lived just metres from where shrapnel showered the road.They were killed instantly, with one man's body blown across the road while the other remained in the vehicle, secured by his seatbelt.The tattooist was a suspect in the 2008 Gouger St shootings, his Enfield home raided by STAR Group officers hours after the gun battle.Yesterday, he returned home to his wife and children, but stayed only five minutes.A uniformed police officer stood about 40m away, guarding the crime scene around Thursday's bomb blast."Get that camera off the house," he shouted while rushing at a television cameraman. "Haven't you got any respect for my kids and wife? Is this how you protect the community, you maggots? Insects. Dogs."The tattooist has a criminal history dating back to when he was 17, including numerous convictions for serious assault and drug dealing.Yesterday, bikie expert and author of The Brotherhoods, Inside the Outlaw Motorcycle Clubs, Professor Arthur Veno said Adelaide was most likely in the middle of a turf war between drug dealers. "It's extremely unlikely that the (motorcycle) clubs are doing this," he said."The clubs are desperately trying to get rid of these guys."They have to distance themselves from the criminal element because the understanding is if they want to keep their club, they need to get rid of that kind of thing. It's much more likely to be an underworld drug situation or turf war."Prof Veno said if the New Boys wanted a war with one club, they would be shut down by all of them. He said the once-warring bikie gangs had been brought together by the United Motorcycle Council to fight the state government's anti-bikie laws."If the New Boys are declaring a war on one club, they can expect to cop it from all clubs, who will join together and stop it real quick," he said. "The bikie clubs are under so much pressure and they've reached a consensus through the United Motorcycle Council that they will push out the criminal element."They are desperately trying to keep a lid on things.
