A used car dealer convicted of “clocking” 11 years ago has been ordered to repay a further £146,000 in criminal gains assets.

Akif Rashid Butt, from Pudsey, West Yorkshire, was jailed for six months and ordered to pay £154,000 of more than £890,000 in gains made through illegal dealings back in 2006, following an assessment of his available assets by the National Crime Agency’s (NCA) Assets Recovery Agency (ARA).

But a financial investigation by the NCA’s Asset Confiscation Enforcement team later found that the 52-year-old had retained assets on which the original confiscation order was based, having paid the sum using other funds.

Reporting from Bradford Crown Court on Friday, The Bradford Telegraph and Argus newspaper said that Butt accepted that the available amount in the confiscation order granted in 2009 be increased to £300,000, in light of the uncovering of new assets.

The amount is to be paid within three months, with a period of 27 months imprisonment in default, it said.

Andy Lewis, head of asset denial at the NCA, said: “Over ten years had passed since Mr Butt was served his initial confiscation order, and it’s likely he thought that he had got away with retaining assets subject of the original confiscation order.

“This should serve as a reminder to criminals that there is a debt to be paid for criminal activity, and the NCA are relentless in their pursuit of criminal assets.”

Butt was originally arrested in 2006 after West Yorkshire Trading Standards officers swooped on his Car R Us used car dealership on Leeds Road, Shipley.

It was discovered that Mr Butt had been reducing the mileage of high mileage vehicles to sell to unassuming customers between May and September in 2005.

He later pleaded guilty to 15 offences relating to 12 vehicles.
