New bikie suspects for NSW shooting murder

Police believe at least three men with links to an outlaw bikie gang gunned down a car enthusiast outside his NSW Central Coast business four months ago.

They say they are close to tracking down the killers who shot Laurie Starling on July 24 outside his car restoration business in West Gosford.

Mr Starling was a popular figure in the motor industry and involved with the annual Canberra-based motor festival Summernats.

The State Crime Command officer in charge of the case, Inspector Grant Taylor, says police have very strong leads.

"We're also confident that the people who committed the actual shooting are not from the Central Coast," he said in a statement on Tuesday.

"We have information to suggest they were from out of town, but were probably collaborating with people from the Central Coast in planning the shooting."

While the shooters have been linked with a bikie gang, the 29-year-old victim was not known to police, who previously said he appeared to be the victim of a brutal and callous murder.

The shooting is believed to have been targeted.

Mr Starling, described by his family as a gentle giant, was leaving his business The Chop Shop when he was gunned down in the driveway just after 7.30pm.

His death sent shockwaves through the motoring community.

Locals said in July that the street was a popular haunt for Rebels club members.
