A DRUGS "Mr Big" is facing an extra seven years in jail after failing to hand over the £2.4million profit of his crimes.

Ayub Khansia, 48, who lived in Tintern Crescent, Blackburn, was ordered to pay back the money he made from heroin supply and laundered by buying 18 properties.

But his year-long deadline to hand over the cash has passed and Khansia, already serving a 12-year sentence, has only paid a small fraction back.

Now police and the Crown Prosecution Service are taking steps to invoke the seven-year jail sentence that Khansia was told he would face if he did not settle the bill.

Officers also warned that Khansia's failure to pay did not mean he would be let off the bill.

Khansia still owes them more than £2.3million - and the authorities are adding interest on so the amount he has to payback is increasing by the month.

And the CPS is warning that unless Khansia co-operates and sells off the 18 properties in his portfolio, they will take steps to seize the assets.

Khansia was ordered to pay back £2.2million within 12 months under a drugs trafficking act confiscation order.

And a further £178,000 was demanded within six months under the proceeds of crime act.

Other members of his family were ordered to payback £500,000, making the Khansia's bill the biggest ever confiscation order in Lancashire.

It is understood his relatives have paid back their share.

Robert Marshall, chief crown prosecutor for the CPS in Lancashire, said: "The sentencing Judge ordered that if Mr Khansia didn't settle the confiscation order he would have to serve extra years in prison.

"The courts will be taking steps to enforce this additional sentence.

"Serving the extra time doesn't wipe out the debt though and the CPS and police will be taking steps to recover the money.

"The options open to us include the appointment of a receiver who can seize and sell Mr Khansia's assets."

The investigation into the family started when Ayub Khansia was arrested in January 2004 at a house in Swallow Drive, where police seized 1.5kg of heroin worth around £150,000.

Khansia was jailed in November 2004 after a court heard how he ran a heroin factory which produced £10 wraps for dealers to sell to addicts.

At the time police said he was second only to the international gang lords who import drugs into the country.

He pleaded guilty to supplying heroin.

Khansia also admitted money laundering as did his son Salim Holden, 27, daughter Anisa, 23, nephew Imran, 24, and father Yusuf, 78.

They were each given custodial sentences.

The police team behind the raids, known as Operation Exclusive, were also honoured by the government earlier this year, winning the Best Practice in Asset Recovery category award in the 2006 Home Office Tackling Drugs Supply Awards.

During the operation, Lancashire police worked with the North West Regional Asset Recovery Team, a branch of the government which works to claim back the proceeds of crime.

The money confiscated goes back to the government to help fight crime.

A spokesman for Lancashire Constabulary added: "We have been informed that there will be a meeting with the Crown Prosecution Service this week to decide the future of this case."
