Spanish police say they have arrested a former JPMorgan Chase trader wanted for allegedly falsifying bank records to cover up $6 billion in trading losses.  http://www.nytimes.com/2013/08/28/business/former-jpmorgan-employee-arrested-in-spain.html?hp&_r=0   A statement said that Javier Martin-Artajo, 49, was arrested Tuesday after he presented himself at a police station in Madrid.
U.S. prosecutors earlier this month filed criminal charges against Martin-Artajo, a Spanish citizen, and another ex-JPMorgan trader, Julien Grout.
Martin-Artajo and Grout were accused of marking up the market value of an investment portfolio to hide its plummeting value. The portfolio eventually incurred a $6 billion loss, which was attributed for months to Bruno Iksil, a trader who became known as the “London Whale”.
Martin-Artajo was to be brought before the National Court in Madrid as part of extradition proceedings.
