Nearly eight years after his death, police are renewing a $100,000 reward for information about the two thieves who drove away with Mr Chin, 33, clinging to the driver's side window of the vehicle in a desperate bid to stop the theft.

Mr Chin, also known as Marcus, had moved to Australia from Malaysia just five months before his death and had taken a job as a furniture delivery driver.

His wife and five-year-old daughter were visiting him from Malaysia at the time, and had hoped to move permanently to Sydney when Mr Chin had established their home.

Mr Chin and a co-worker were delivering a massage chair to a townhouse on Kerrie Crescent in Peakhurst on October 30, 2006 when two thieves saw the delivery van parked in the driveway with the keys in the ignition.

When Mr Chin heard the van's engine start, he ran down the driveway and put his arm inside the open driver's side window in an attempt to turn the engine off, but he fell as the van turned left into Henry Lawson Drive.

The van's rear tyres ran over his body, and he died from his injuries.

The van was found abandoned less than one kilometre away in Riverwood.

At the time, policed said Mr Chin's death appeared to have arisen from a crime of opportunity when the two thieves saw the van parked in the driveway.

The thieves, thought to be aged in their 20s, were likely to be locals or have good local knowledge as the van was found abandoned such a short distance away, police said.

Mr Chin's uncle Michael Wong will join police on Monday to make a fresh appeal for information about the identity of the thieves.

The $100,000 reward has previously been offered.

Anyone with information has been urged to contact Crime Stoppers on 1800 333 000 or visit the Crime Stoppers online reporting page.
