The Derry public are being warned over a rise in the number of people being targeted by scamsters.
Police say con artists have targeted people in Eglinton recently in a computer-based scam aimed at eliciting personal details.
A PSNI spokeswoman says the scam involves people receiving a telephone call from someone reportedly from a well known software company claming their computers had been hit by a virus.
She says police are warning local people to be vigilant and protect themselves against unscrupulous criminals who are constantly identifying and developing new methods to defraud innocent people.
“Police would advise that personal details never be disclosed to unsolicited callers or via email or online.
If you have any concerns or require any further advice or information please feel free to contact your local crime prevention officer on 0845 600 8000,” she says.
Meanwhile the Office of Fair Trading (OFT) is also warning local people especially the elderly and vulnerable, to be on their guard against rogue traders knocking at their door.
Anyone with any concerns about rogue traders is urged to call Consumerline on 0300 123 6262 or visit www.consumerline.org
