A £25,000 reward is being offered in a bid to catch conmen who targeted cash machines in Sudbury.
Police warned people in the town to take care when withdrawing money from ATMs after cloning devices were found on cash machines outside Waitrose in Station Road and Santander in Old Market Place last month.
Both devices were discovered within the space of three days.
Although the devices were spotted before anyone fell victim, Inspector Paul Crick, from Sudbury Police, warned that attempts to obtain bank card information in this way was usually carried out in spates.
Since the discoveries, Crimestoppers has teamed up with Link – the UK’s cash machine network – to offer up to £25,000 for any information relating to the Sudbury incidents.
“We’re urging the public to come forward with any information that they may have about cash machine crime,” said Graham Mott, a Link spokesman.
“Even something that may sound insignificant could be part of a bigger picture and prove invaluable in convicting someone involved in cash machine crime.”
Link has also compiled a guide for ATM users to follow to avoid falling victim to card cloning.
l Scan the whole ATM area before you approach it and avoid using the ATM if there are suspicious-looking individuals around.
l Check to see if anything looks unusual or suspicious about the ATM showing it might have been tampered with. If it appears to have any attachments to the card slot or key pad, do not use it.
l Stand close to the ATM and shield the keypad with your hand when keying in your PIN.
l If your card gets jammed or retained by the machine, report this to your bank or building society immediately.
l Check that others in the queue keep a good distance from you.
l Keep your PIN secret.
l Be especially cautious if strangers try to distract you or offer to help at an ATM.
l Regularly check your account balance and keep your receipt to check against your statement.
