Police are seeking two men as part of an investigation into an abandoned truck that rolled on a major highway in Sydney’s south-west containing 3,000 litres of stolen fuel.

Emergency services were called to the M7 at Horsley Park after about 8:30am on Monday and found an overturned tabletop truck that was unoccupied and spilling a small amount of diesel.

Two men, believed to be the driver and his passenger, fled the scene before officers arrived.

The driver had rolled the truck while trying to perform an illegal U-turn in the middle of the highway.

Detectives from Fairfield police discovered the men had attended a nearby service station prior to the crash and stolen 3,000 litres of diesel fuel that amounted to $6,300.

The stolen fuel had been stored in three different containers, according to police.

Superintendent Michael McLean, commander of Fairfield police, said it was unclear what the fuel was intended to be used for.

“I think on the main people expect they’ll conduct their business honestly. On this occasion that hasn’t occurred obviously,” he said at a press conference.

“What it does show is that people will go to any lengths to continue their enterprise, whatever that may be, and not conduct themselves in the lawful manner.”

He said police were making inquiries with the company which rented out the truck.

There were no injuries reported as a result of the  incident.

However, the crash caused major delays, with south-bound traffic banked back to Rooty Hill.

“We’re lucky no one was killed or seriously injured, but certainly that inconvenience to motorists can’t be understated,” Superintendent McLean said.

Police have released descriptions of the two men they are seeking.

The driver – a man believed to be in his 30s or 40s – was wearing a white cap, orange/black Hi-Vis t-shirt, orange/yellow shorts and grey shoes.

The passenger – a man believed to be in his 20s or 30s – was wearing a dark blue/black coloured hooded jacket.

Any witnesses or anyone who may have dash cam vision is urged to contact police or Crime Stoppers.
