Thieves in Fife are using a sophisticated “override” device to unlock Ford Transit vans.
Officers said a number of thefts occurred between Monday 9 and Tuesday 10 May.
Transit vans were targeted in the Kirkcaldy, Cowdenbeath and Dunfermline areas with high value tools and machinery stolen.
The culprits are suspected to have gained entry to the secured vans by means of a device that can override the locks.
The device does not leave any damage on the vans.
Owners of similar vehicles have been warned not to leave any valuables in their vehicles and to report any suspicious activity to police.
Detective Sergeant Kieran Marsh said: “We are investigating a number of similar incidents throughout Fife where Ford Transit vans have been targeted.
“These vans were secure, however the persons responsible appear to have used some form of device that allows them to gain access to the vans without causing damage, before stealing work tools and machinery.
“Three males were seen acting suspiciously in the Johnstone Park area of Cowdenbeath during the early hours of Tuesday May 10. These individuals made off in a white Ford Transit pick-up style van.
“We are pursuing a number of lines of inquiry, however I would appeal to anyone who observes any suspicious activity to contact police via 101 or anonymously via Crime stoppers on 0800 555 111.”
