Lorry drivers in South Yorkshire are being urged to be on their guard against thieves stealing fuel.
Diesel worth more than £1,000 was stolen from lorries parked at an industrial estate on Meadow Way, Swinton, Rotherham, while drivers slept overnight on Sunday into Monday.
Another lorry, parked at Kilnhurst Road, Rawmarsh, was also targeted between 6pm on Sunday and 3.25am on Monday.
Police said the driver of that lorry heard a noise at the back of his vehicle and climbed out of the cab to find a siphoning hose near the tank.
The culprit had fled.
Officers believe the incidents may be linked and are issuing warnings to drivers and businesses in the area.
PC Andy Robinson, crime reduction project officer, said: “We’d urge drivers to use secure truck-stop facilities, which will be well lit, have CCTV and mean they’ll be alongside other lorry drivers, rather than parking in a lay-by or close to their drop off point.
“The nearest truck stop in Rotherham is at Hellaby.
“I’d encourage business people to spread this message to delivery drivers, because if thieves can steal fuel from a wagon, they could also potentially steal the load that’s being carried.”
PC Robinson said that drivers for local hauliers should not fill up vehicles at night so they are ready to leave yards in a morning, as it might make them susceptible to theft.
He said: “We’ll be looking to put up crime prevention posters, where appropriate, to give people advice.”
South Yorkshire Police launched Operation Lockdown last year to crack down on burglary and vehicle crime, after a rise in both offences between April and August.
So far more than 1,000 suspects have been arrested for various offences.
n Witnesses to the fuel thefts, or anyone with information about those responsible, are asked to call South Yorkshire Police on 101 or Crimestoppers, anonymously, on 0800 555111.
