POLICE are warning people to be on guard after thefts from cash machines in Pocklington town centre.
A device was fitted to two ATM machines in Market Place to prevent money being dispensed to customers.
It is believed the thieves then later returned to the machines to retrieve the device and steal the cash, which had been dispensed but collected within the illegal device.
The first incident was reported as happening at 7.15pm on Wednesday 29 February at the ATM outside Barclays Bank, with a further two thefts taking place between 7.22pm on Monday 12 March and 8.40pm on Wednesday 14 March.
Another incident was reported as happening at the ATM outside Lloyds TSB between 7.15pm and 8.45pm on Wednesday 14 March.
Police are looking for two white men in connection with the incidents, who are both believed to be in their late 20s or early 30s. The first is said to be stocky and was wearing a blue, zipped hoody, blue jogging bottoms, white trainers and a cream baseball cap. He also has a closely-trimmed brown beard.
The second is described as being of medium build and was wearing a navy beanie hat with a peak, a padded Barbour-style jacket, dark jeans and trainers.
Police have warned people to be vigilant when using cash dispensing machines.
A police spokesman said: “If a cash machine appears to have been tampered with, please report this to the bank or to the police.
“Some of the devices used are very well designed and can often be difficult to spot. Do not be afraid to ask the question of the bank, if you suspect anything suspicious.
“If you believe your debit or credit card has been cloned, alert your bank, building society or credit card company immediately. They will then be responsible for taking the investigation further and, where appropriate, reporting the fraud to law enforcement.
“If you would like further information about fraud you can speak to an advisor at Action Fraud on 0300 1232040 or visit the Action Fraud website or visit crimestoppers website www.crimestoppers-uk.org.”
Anyone with information about the ATM thefts in Pocklington is asked to contact Humberside Police on the non emergency number 101, quoting log number 278 of 1 March.
