Dyfed-Powys Police is investigating a number of reports of a man purporting to be a police officer from the London area.

The man, who sometimes gives the name PC or DC Lawrence, has attempted to scam residents into believing their bank cards have been used fraudulently.

Anyone who receives such a call is asked to contact Dyfed-Powys Police either online or by calling 101.

"The man is contacting local residents to discuss details of an incident in which their card has been used fraudulently," said a police statement.

"He is then asking that residents call a number he provides to obtain a crime reference number.

"On some occasions he has stated he is either PC or DC Lawrence.

"We are asking the public to remain vigilant, report any suspicious calls and follow the below advice.

"Make a note of the callers details, including name, rank, collar number and station.

"Note any contact details from caller display, or via 1471 after the call has ended. Block the number that called you. 

"End the call. Say you will contact the police directly to confirm the caller’s identity and be put through internally.

"Ring a family member before you make your next phone call. This is to make sure the line has disconnected from the initial (suspected fraud) caller.

"If anyone calls at your address following this suspected fraud caller, call 999.

"Don’t hand out any personal or financial details, engage in conversation, or make any arrangements to hand over any cash or card.
