A father and son from Birmingham claimed they made their fortune from winning the Pakistani lottery a remarkable 123 times, a feat that would be equivalent to winning the UK National Lottery jackpot 40 weeks running.

Kashaf Ali Khan, 44,

81-year-old Malik Abdullah Farooq and his son Kashaf Ali Khan, 44, claimed their incredible run of fortune lasted between July 2012 and February 2013, which allowed Farooq to purchase a lavish £412,000 house.

But the National Crime Agency became suspicious and employed an expert statistician who said the likelihood of the incredible run would be equivalent to winning the UK National Lottery jackpot 40 weeks running.

Khan had previously admitted money laundering offences in September 2010 and was ordered to pay £175,000 in 2012 because of the conviction.

Despite Khan having no recorded legitimate source of income, he paid off the £175,000 in cash within 12 months.

He has now admitted paying off the confiscation order using further criminal cash.

In 2013 he used his father’s funds to buy the Prospect Lane property.

During the previous year, flurries of money from Dubai were paid into Farooq’s Pakistan bank account.

Farooq used black-market prize bond dealers in Pakistan a bid to fool investigators into believing he had won legitimate prizes.

Winners of the Pakistan state lottery have to wait several weeks to collect their winnings.

Because of that, some are willing to sacrifice an amount by selling their winning ticket to an agent for a lesser sum which they get immediately

The black-market agents then sell on the winning tickets – for more than they are worth – to crooks needing to clean their criminal money who can then get prize organisers to issue payment in their name.

NCA senior investigating officer Phil Houghton said: “Kashaf Ali Khan has admitted two counts of money laundering because of the weight of evidence against him.

“He thought that he had the perfect explanation if questioned about how he funded the house purchase.

“He and his father possessed documentation to support their story of being genuine winners of the Pakistan prize bond scheme.

“Khan didn’t account for NCA investigators discovering the scheme’s black market and proving he had used it to clean criminal money.
