As the saying goes, if something seems too good to be true then it probably is - and this is definitely the case in this type of situation as riches are promised simply for contacting the phone number supplied.

A spokesman for Cumbernauld Police said: "The scam, in this instance, originating from Nigeria, promises untold riches simply for supplying some personal details.

"Confidence tricksters and thieves are always thinking up new ideas on how to separate you from your hard-earned cash. So please, always be on your guard when some opportunity appears out of the blue."

Do NOT be tempted to contact them, do NOT supply any further unsolicited personal details and do NOT give out any credit or account numbers under ANY circumstances.

Their message is simple: don't give the thief a chance.
