Police try to stop bikie death payback following shooting of Hells Angel Tyrone Slemnik POLICE investigating the murder of a bikie in Sydney's eastern suburbs have made contact with rival gangs in a bid to halt further bloodshed. "We have spoken to them on the phone and are negotiating a face-to-face meeting," NSW Homicide Detective Inspector Dave Laidlaw said. Police are investigating the death of Hells Angel Tyrone Slemnik in Eastlakes on Monday night. A 25-year-old associate was also wounded when at least two gunmen opened fire on a group of men outside a George St unit block. One possible motive involves a long-running battle between the Comanchero motorcycle gang and the Hells Angels, who are trying to expand into the eastern suburbs. "The wounded man has been interviewed in hospital and we will be talking to him further," Insp Laidlaw said. He said a number of possible motives were being looked at. Slemnik, a father of three, was due to be sentenced next week for attempting to extort money from an inner-city brothel owner last October. Documents tendered to the Downing Centre Local Court ahead of Slemnik's sentencing for demanding property with menace claimed he told Fallen Angels owner Linda Wang: "You must give me $2500 or we will come and smash your shop. You have 10 days. The documents said Slemnik, who had a court history going back to 1999, left the brothel but called Ms Wang nine times in 30 minutes, although she was too frightened to answer. The court heard Slemnik and his co-accused Aiden Garard, due to be sentenced next week, never went back to the brothel to collect the money. Slain bikie was due to be sentenced over extortion Both pleaded guilty to the charges and were on bail awaiting sentencing. "Tyrone said he might be locked up for a little while," his father Ricko said yesterday. I told him to stay out of trouble but young people don't always listen to you. Mr Slemnik said his son, girlfriend and daughter visited him last week. "He was a good father and even though he got in some trouble he would not hurt anyone," Mr Slemnick said. My daughter rang me and told me 'Tyrone has been shot' ... and that we had to go and see the police. Slemnik is survived by three children to three different women. Family and friends remembered Slemnick as a "true warrior" who was "always making people laugh." "Today my heart bleeds n my body is empty im going to miss you so much baby brother," Sister Marija Daley Slemnik wrote on Facebook.
