More than £100,000 worth of fake goods were seized yesterday from a car boot sale in an operation aimed at organised crime gangs.

Trading standards and police officers arrested five men and seized the goods at the regular Sunday morning car boot sale in Bingley.

It was teeming with around 400 people as five teams of plain-clothed officers swooped at 10am.

Latest movie releases, including King Kong and Lassie, were taken along with CDs, Nike trainers, illegal pornography, and imitation Louis Vuitton, Fendi, and Burberry designer handbags.

The sting was swiftly followed by searches at the homes of the men, four of whom are from Bradford.

Uniformed officers also descended on the home of the fifth man in Leeds where they say they uncovered a "massive" factory for making counterfeit DVDs.

Trading Standards officers said there were enough copying machines and recording equipment to create 40 discs every 30 seconds. Paul Smith, principal officer for West Yorkshire Trading Standards, said a factory of the kind discovered could be generating between £50,000 to £60,000 of income every year.

Mr Smith said: "Bingley Market is not a massive car boot sale but this is a significant find for the whole of West Yorkshire, and does not happen very often.

"The operation has been a major success, and this has made a significant dent within the criminal fraternity of West Yorkshire."

Police officers from across the district joined ten trading standards officers, 35 plain-clothed special constables, and PCSOs to make the arrests.

It is the only time special constables have been deployed in a large plain-clothes operation anywhere in the country.

Sergeant Mark Eilbeck, who planned the operation, said the swoop followed three weeks of intelligence gathering by police and Trading Standards as part of an operation dubbed ACE.

Sgt Eilbeck said: "Bingley market has become the hold of some well-known criminals who have been displaced because of our success in targeting them, and are turning away from large scale heroin dealing and turning to softer crimes."

He added: "The estimated income from these gangs has quadrupled because they have moved away from heroin and there is not as much competition in counterfeit goods."

Inspector Owen West of Keighley police said: "The feedback from residents in the area has been tremendously positive with many officers being stopped and praised for their work."

He added: "The operation has been an unrivalled success far exceeding the expectations of both the police and trading standards.

"This sends a strong message to the criminal fraternity in West Yorkshire that the sale of counterfeit goods will not be tolerated and further large scale operations will follow in the near future in the surrounding area.

"Offenders be aware, if you are located in this area Operation Target will be coming for you."

Five men today continued to be questioned by police in connection with the incident.
