Sergeant Damien Bartley, crime prevention officer for Longford-Roscommon, has these tips for avoiding investment scams.
"Search crypto currencies before making any investments. There are many different types. Do not respond to pop-up ads, social media ads, messages, and do not follow links from pop-up ads on social media. Always be wary of unsolicited contact from persons unknown. Be very wary when the investment is being endorsed by a celebrity or famous business people. They may not know their name is attached to the advertisement. Do not download suggested apps and never allow another person to take control of your computer".
