More than a ton of illicit booze was seized by officers out on a day of action saving taxpayers thousands of pounds.
Harrow & Wealdstone Food & Wine, in Masons Avenue, was one of four shops inspected by officers on Wednesday last week, with all the alcohol within the store removed as officers believed it had been purchased from a supplier looking to dodge paying the tax man duty on their goods.
Officers from Her Majesty's Revenue and Customs (HMRC) teamed up with Harrow bobbies for the operation, which is the sixth in Harrow police's Secure Streets operations .
Simon Fretwell, strategic advisor to Harrow's police borough commander, organised the operation and said: "It was a huge success. We took so much alcohol that roads had to be closed to facilitate a lorry to pick it up and the customs officers are still counting it.
"This was definitely one of the biggest hauls we have taken, if not the biggest.
"Bringing in alcohol that has not paid duty allows traders to sell a can of larger for a pound, where businesses who are bringing alcohol in from honest suppliers are having to sell them at £1.79, so it is the honest ones who are losing out."
Customs officials are conducting investigations which could see businesses selling the alcohol closed down.
"This acts as a message to other businesses to sell the legal goods or we will shut you down," Mr Fretwell added.
The HMRC claim that counterfeit alcohol costs the taxpayer around £1billion a year.
Alongside the seizure of the counterfeit alcohol, there were four arrests for drug-related offences as Harrow's police officers teamed up with Harrow Council and London Fire Brigade for their latest day of action, with the intention to carry one out in each ward in the borough.
