A UK trader accused of contributing to the 2010 Wall Street "flash crash" has protested his innocence in court, saying he did not "do anything wrong". Navinder Singh Sarao, 36, has been charged with wire fraud, commodities fraud and market manipulation by the US Justice Department (DOJ). Mr Sarao denies the charges but was remanded in custody for the third time after failing to raise £5.05m in bail. His lawyers' request that bail be lowered to £50,000 was refused.
