UK court dents "flash crash" trader's hopes of bail release

Navinder Sarao, 36, was arrested by British police on a U.S extradition warrant on April 21 after being charged with wire fraud, commodities fraud and market manipulation by the U.S. Justice Department. He had applied for his bail conditions to be relaxed after his assets were frozen.

But Judge Ross Cranston turned down his application.

"There's no substantial reassurance that this applicant is not a flight risk," he said.
