Tools worth thousands of pound were stolen after four work vans parked in Sheffield were targeted on the same night, police have revealed.
South Yorkshire Police are warning workers to remove all their valuables from their vans to avoid becoming the next victim.
One van parked on Eastcroft View, Westfield, had a power drill and other tools valued at £600 taken, while another parked on Gleadless Avenue, Gleadless, had tools worth more than £1,000 stolen.
Would-be thieves also caused damage to two vans parked in Thornbridge Drive, Frecheville, and Farmview Drive, Hackenthorpe, although nothing was stolen.
They were all targeted overnight on Monday, December 2.
Detective Chief Inspector Zaf Ali said: “I want drivers to remain security conscious about their vans at the end of the working day – including over the weekend when they’re not at work.
“Thieves are targeting you and we do not want you to be a victim of crime, losing tools that may affect your livelihood.
“If possible vans should be emptied of tools and parked in positions such as reversed against building walls, making entry difficult for anyone attacking your van.”
