Police say the digger was taken from the nearby Longfield Road recycling centre, and was used to smash into Asda supermaket on the same road.
Detective Inspector James Derham said: ‘The cash machine burglary took place in a busy industrial area of the town and we are asking for witnesses who may have seen anyone acting suspiciously or saw a large vehicle leaving the north farm estate area around the time of the incident.’
He said Kent Police received a report at 3.34am on Thursday 4 April 2019 that a digger had been driven into Asda in Longfield Road, causing damage to the building, and a cash machine was stolen.
The digger was abandoned in the car park of Asda in Tunbridge Wells in the small hours of this morning.
The ram-raid caused a large amount of damage to the outside wall of the supermarket where the ATMs are located.
