NEW YORK, Rajab 12, 1436, May 1, 2015, SPA -- U.S. prosecutors said Friday their efforts extradite from Spain a former JPMorgan Chase & Co executive charged in connection with the bank's $6.2 billion "London Whale" scandal had hit a dead end, Reuters reported. In a filing in Manhattan federal court, prosecutors said Spanish authorities have decided not to appeal an April 23 ruling by a court rejecting the extradition to the United States of Javier Martin-Artajo, a Spanish citizen. The filing came in a civil lawsuit brought in 2013 by the U.S. Securities and Exchange Commission against Martin-Artajo and another trader, Julien Grout, who were charged criminally at the same time. The Spanish court's decision effectively has left both men out of U.S. prosecutors' reach. Grout lives in France, which does extradite its own citizens. With extradition off the table, prosecutors under Manhattan U.S. Attorney Preet Bharara said they no longer are seeking to delay depositions in the SEC's case. -- SPA 23:49 LOCAL TIME 20:49 GMT www.spa.gov.sa/w
