Restaurants have been urged to remain vigilant following an increase in cooking oil thefts.

The warning came from North Wales Police on Thursday morning.

A spokesman said: "With the rising costs of fuel across the country, we are seeing thefts of cooking oil and an increase on suspicious activity surrounding this.

"Recently, we had an incident where two males approached a restaurant in Broughton claiming to be from the Environmental Agency there to collect their waste cooking oil. Luckily the staff member was aware of fraudsters making these claims, asked for ID which was clearly not genuine and sent them away.

"Cooking oil is sought after to be used in the production of Biodiesel.

"Please be mindful should this relate to your business, of where your cooking oil is stored and the security measures around your property due to the increase in thefts.

"Any suspicious incidents like this, report to 101.

"If you are unsure if they are genuine, contact your regular waste oil collector to confirm."
