A gang of five used a JCB to smash their way into a building society and steal a cash machine.
The attack took place inn the early hours of this morning at the Halifax branch at King Street in Saffron Walden.
Police say five suspects used the digger to pull the machine free before it was loaded into a white van. It's also believed two other vehicles, a silver and white car, were with the van as it left the scene.
The police helicopter was sent up but couldn't trace the suspect vehicles.
Police would like to hear from anyone who has information, CCTV or dash cam footage.
