Increase in cash machine PIN and card thefts

People are being warned to be on the lookout for criminals sneaking a look at their PIN numbers and stealing their cards to get hold of cash.

Incidents like this at cash machines have tripled since last year.

The police and banks have been cracking down on high-tech fraud like card reading devices - but while they are making some advances, the fraudsters are now opting for more low-tech cons.
