A digger has been used to steal a cash machine from a building society in a Buckinghamshire town.
Two or three people are believed to have carried out the raid at the Nationwide in High Street, Olney, at about 0200 GMT.
Witnesses told Thames Valley police they saw a digger being driven at the shop front.
They then saw the cash machine being removed and loaded on to a flatbed lorry before it was driven away.
A police spokeswoman said it was not yet known how much cash was stolen.
