Man charged over Sydney gangland murder

Homicide Squad Commander Detective Superintendent Danny Doherty said that while the accused was not the gunman he was allegedly directly involved in planning the murder and had also been charged with being part of an organised crime network.

"Whilst he didn't pull the trigger ... he might as well as loaded the gun," he told reporters on Thursday.

"We are alleging he was part of a sophisticated and meticulous planned murder plot."

Ahmad, 39, was gunned down on the street in Greenacre in Sydney's southwest in April, six months after being released from jail, having served five years for the manslaughter of gangland rival Safwan Charbaji.

At the time detectives described the hit as another brazen and callous chapter in Sydney's ongoing gang wars.

He had been warned underworld enemies placed a $1 million bounty on his head.

His brother and crime kingpin Walid "Wally" Ahmad also died in a hail of bullets while sitting at an outdoor cafe at Bankstown in 2016.

Det Supt Doherty said Ahmed's murder would not have happened without careful planning and co-ordination.

"It takes a number of people ... to commit a sophisticated and well-planned execution of an organised crime figure," he said.

The accused man had fled overseas shortly after being questioned by police in May, before returning on October 31.

"So the message is, whether you go overseas or go interstate or you stay where you are police will still ... work tirelessly in relation to building evidence," Det Supt Doherty said.

Police would be "unrelenting" in hunting down people involved in organised crime murders, he said.

In July, NSW Police arrested a 37-year-old they alleged was involved in planning Ahmad's killing, a month after a 49-year-old man was charged with being an accessory before and after the fact to the murder.

The investigation is part of ongoing inquiries by Task Force Erebus into 14 fatal shootings and criminal activities by organised crime networks across Sydney.
