Businesses have been given a heads-up about a suspected telephone scam being investigated by police.

Companies are contacted by phone with a warning that their accounts are under attack, and fraudsters then use convincing techniques – including supplying numbers which appear to be legitimate – to gain access to business accounts and empty them of cash, causing huge losses to companies.

Det Insp Nick Power of the multi-force Eastern Region Special Operations Unit said: “This is a very alarming trend in which reputable, knowledgeable firms are falling victim to these highly believable cons. We are currently investigating a number of reports.”

Business owner are urged to remain vigilant and report any suspicious activity to their local police force using the 101 number.
