A trader dubbed the Hound of Hounslow has lost his fight against extradition to the United States.

Navinder Sarao, of Clairvale Road, Heston , is accused by the US government of contributing to the 2010 flash crash , which wiped £570bn from the stock market in less than five minutes.

District judge Quentin Purdy ruled at Westminster Magistrates' Court on Wednesday (March 23) that the 37-year-old could be sent to the States for trial, as his alleged offences do constitute crimes in the UK.

Mr Sarao, who attended Brunel University, faces 22 charges of fraud, manipulation and 'spoofing', which between them carry a maximum jail sentence of 380 years.

Richard Egan, who is representing Mr Sarao, reportedly expressed his disappointment and said his client would definitely appeal the decision.

Tuckers Solicitors, for whom Mr Egan works, told getwestlondon it was not making a statement at this stage.

Accused of 'spoofing'

Mr Sarao is accused by the US government of earning £27m through "spoofing" - the act of placing and quickly withdrawing offers to drive down prices and make a profit.

He is alleged to have made the money operating from the bedroom of his parents' home, using an automated computer programme.

Mr Sarao, who is said to have Asperger's syndrome, denies the charges. But his lawyers had argued that even if the allegations were true he would not have broken UK law as there is no such offence as "spoofing" in this country.

Research recently published by academics in the US suggested Mr Sarao's actions were "highly unlikely" to have led to the flash crash .
