A warrant has been issued for the arrest of a man who allegedly killed one innocent victim and wounded two others in a bungled underworld hit.
Police allege Anthony Pele, 22, fled overseas soon after pulling the trigger on all three victims in an early-morning attack in southwest Sydney.
Ahmed Al Azzam, 25, died in hospital three days after he was found seriously injured in his parked car following the shooting at Greenacre on July 23.
Two other people, a 22-year-old man and a 19-year-old woman, were wounded in a separate car parked about 50m away.
Four people were charged with playing various roles in Mr Al Azzam's alleged murder on Wednesday, but investigators said the gunman was yet to be found.
Later that night, police said detectives probing the Greenacre shooting were granted a warrant for the arrest of Pele.
Investigators believe he opened fire on both of the parked cars in an attack linked to the Haouchar crime gang, which wrongly thought the occupants were members of the rival Comancheros who were planning a kidnap attempt.
Acting Detective Superintendent Virginia Gorman urged Pele to come home and face the consequences of his actions.
"He is an Australian-born man, he has grown up here in Australia," she said on Thursday.
"He will know people here who know where he is.
"We're appealing to those people to give us information as to his whereabouts."
NSW police are working with international agencies to determine which country Pele is in and bring him back to Sydney.
"The arrest warrant is forever and until he is arrested this will continue," Det Supt Gorman said.
Three men have been charged with Mr Al Azzam's murder, while a fourth is accused of being an accessory before the fact of the killing.
They were among eight people arrested in Sydney and on the Central Coast on Wednesday in simultaneous raids that police said had helped effectively dismantle the Haouchar gang.
