Akram Ul-Haq, 37, of Emerald Road, was convicted of several counts of money laundering and laundered £1.3 million of money from a firm of solicitors.
He was also convicted of conspiracy to commit fraud, alongside Nighat Sultana, 35, also of Emerald Road. The two stole £176,000 from a Chinese company, and £98,000 from an Israeli company.
The offences began in September 2011. Victims from China and Israel travelled to Luton in 2012 to report their crimes, and following extensive investigations by Bedfordshire Police, the two were arrested on 24 September 2012.
Investigation Officer Gary Hales said: “The duo carried out a number of offences, taking a great deal of time and effort to deceive the victims out of large numbers of money.
