A trader dubbed the 'Hound of Hounslow ' who is accused of contributing to a 'flash crash' on Wall Street is set to learn his fate in March.

Navinder Sarao, of Clairvale Road, Heston , is fighting extradition to the States, where he is wanted to stand trial for illegally manipulating the stock market.

The 37-year-old faces 22 charges in the US of fraud, manipulation and 'spoofing', which between them carry a maximum jail sentence of 380 years.

At the conclusion of a two-day extradition hearing at Westminster Magistrates' Court on Friday, February 5, Judge Quentin Purdy said he would announce his decision on March 23.

The US government claims that, operating from the bedroom of his parents' house, Mr Sarao used an automatic computer programme to artificially drive down share prices for his own gain.

It alleges he earned £27m by 'spoofing' - the act of placing and quickly withdrawing offers he never intended to complete - and helped trigger the 2010 'flash crash' in which £570bn was wiped from the US stock market in less than five minutes.

But Mr Sarao's defence counsel reportedly told the court the former Brunel University student, who is said to have Asperger's syndrome , had not broken UK law as there is no such offence as 'spoofing' in this country.

Mr Sarao, who denies all the charges against him, was granted bail on the same conditions as before.
