WEB users in West Yorkshire are being warned to watch out for scammers pretending to be police.
Officers say while people are trawling the web viewing legitimate websites, users are suddenly faced with a locked computer and a message claiming to be from West Yorkshire Police.
The message claims that the force has identified them as having illegal activity on the computer and that they must pay a fine which varies in amounts, by contacting an email address or telephone number and quoting a voucher code.
Police are urging members of the public to be on the look out for the message and say if it appears on their computers, they must not respond and report it to the police immediately via 101.
It is thought the scam has hit other areas of the country and has just recently come to light in West Yorkshire.
Detective Inspector Fran Naughton of West Yorkshire Police’s Economic Crime Unit, said: “This scam is very deceiving as not only does it use convincing legal jargon, it also misuses the force crest and logo. We currently have had 20 reports of this nature in West Yorkshire over the last few days but we are aware there are more victims of this scam.”
