Thames Valley Police is appealing for witnesses to an attempted theft in Beaconsfield.
At around 4.30am on Saturday (2/2), three offenders damaged a cash machine at the Nationwide Building Society, The Broadway.
It is believed that the offenders attempted to use an explosive to access the machine, but their attempt failed.
Army Explosive Ordnance Disposal officers from the Royal Logistics Corps based at RAF Northolt attended the scene, alongside colleagues from the Buckinghamshire Fire & Rescue Service, and following a thorough search, it was confirmed that no explosives remained.
The first offender was dressed all in black with a hooded top with the hood up and brown shoes.

The third offender was wearing a dark hooded top with the hood up, blue trousers or jeans and white shoes.
No further descriptions are available at this time.
