It’s the third time this year a spate of thefts such as this has hit the town’s tradesmen.
The vans targeted were parked in Priors Road, Forthill Avenue and Elliot Road in the Parkside area of town.
The alarm was raised with police after at least two members of the public came across joinery equipment cases emptied and dumped on roadsides.
Police investigating the string of thefts are appealing to any potential witnesses to get in touch.
A spokeswoman said: “Reports were received from around 4.20am on Friday morning of vehicles being damaged on Priors Road, Forthill Avenue and Elliot Road.
“Tools, worth four figures, have been stolen from some of the vans and numerous empty boxes have been discovered throughout the town.”
Last month two Ford Transit vans were broken into in the town’s Old Station Yard, and equipment worth £1,500 was stolen.
And in early January criminals broke into and steale tools from 12 Ford Transit vans parked in the Howdenburn area in one night.
This third spate has led to outpourings of anger on social media with some residents calling for an increased police presence in the town after dark and others suggesting CCTV should be installed in the worst-hit residential areas.
Complaints have also been shared over availability of so-called ‘skelton keys’, which unlock some vans, being sold for as little as £16 online.
Anyone with information should contact Police Scotland on 101 or Crimestoppers anonymously on 0800 555111.
