Credit Suisse says struck security deal with 'Flash Crash' suspect

Credit Suisse UK entered into a security agreement with Nav Sarao Futures in 2010 that was a standard banking arrangement and not a mortgage, a Credit Suisse spokesman said on Wednesday. Nav Sarao is accused of earning millions through fraud and helping cause a trillion dollar "flash crash" on U.S. stock markets. "A charge was created and registered in May 2010 in favor of CSUK which related to a Security Agreement," the Credit Suisse spokesman said, citing regulatory filings in emailed comments
