A third arrest has been made in an investigation into a bank card scam in Kirklees.
And police are now warning residents to continue to be vigilant and never disclose bank card pin numbers to police or their bank.
Police are investigating at least 12 instances where scammers have phoned people claiming they have been the victim of a bank card fraud and urged them to give out bank details.
Detective Inspector Stef Wiseman, of Kirklees CID, said: “We have received around a dozen calls since the start of December from Dewsbury and Huddersfield residents reporting concerns about phone calls from police.
“The police simply do not operate in this way. We would never ask you to give out financial information over the phone and even if there was a requirement for you to be issued with a new card, neither the police or your bank or building society would ask you to hand over your old card.”
The victims so far have predominantly been Asian families with the caller having details such as their name and address before they make contact.
Two men have been already arrested and bailed as investigations continue.
Anyone receiving a new call is asked to immediately afterwards dial 1471 to check whether there is any incoming call data and then also report the call to the police.
