A judge has ruled that a British financial trader suspected of playing a role in the so-called 2010 "Flash Crash" in stock markets can be extradited to the United States.

District Judge Quentin Purdy said Wednesday that 37-year-old Navinder Singh Sarao can face trial in the United States on charges that he helped trigger the crash, which saw U.S. stock values plunge and rebound within minutes.

Sarao faces 22 charges in the United States for his suspected role in the crash, which saw tens of billions of dollars lost in just five minutes.

U.S. officials say he made $875,000 on that day.

His lawyers say he plans to appeal the Westminster Magistrates' Court decision.
