Residents have been targeted by cold callers posing as detectives investigating credit card fraud.

Police are warning people to be vigilant after three people who live in Whitstable received the phone calls yesterday.

The man claimed he was investigating possible credit card fraud, using that as a pretext to ask about the residents' card details.

All three people became suspicious and contacted police without giving the fraudster any details or transferring any money.

An investigation into the incidents is ongoing and residents are being urged to be on guard against fraudulent callers.

PC Chris Green, of Canterbury's Community Safety Unit, said: “Those who received these calls did exactly the right thing and contacted us on a different phone to that they were called on.

“I urge anyone contacted by someone claiming to be from the police, or from their bank, not to agree to transfer any money.

“Always speak to family or friends before committing to anything involving money, or get independent legal advice.

“Don't be embarrassed about reporting a scam. Because the scammers are cunning there's no shame in being deceived. By reporting it, you'll make it more difficult for them to deceive others.'

Police say in an instance where a suspicious caller is claiming to be an officer, you should stop the call and contact the force to check the alleged officer's identity.

It is recommended to wait five minutes before using your phone after such a call, as there have been cases of fraudsters keeping the line open after a victim has hung up.
