A former Credit Suisse trader accused by U.K. prosecutors of concealing about $18 million of losses after taking inappropriately risky positions won the dismissal of criminal charges after years of investigations.  Rohit Jha, 39, who handled ETFs, had endured a 4-year odyssey. 

Credit Suisse discovered the alleged losses that Jha incurred in December 2012. The police then interviewed him in January 2013. In October 2013, when CS dismissed Jha, they notified regulators of the discovery.  By mid-2015, Jha was charged by prosecutors with fraud by abuse of position and fraud by false representation, and was accused of mis-marking certain ETF positions in a bid to hide the losses and to make a profit for himself.

The judge, however, dismissed the charges because of inconsistencies with evidence that compromised the case. Apparently, evidence showed that Rohit Jha had been "... specifically authorized to act as he did, and had made a profit, not a loss, on a number of the questioned transactions."  

In the meantime, Jha, an Indian national, hasn’t been able to work since he was fired - as his visa was contingent on him working for Credit Suisse. Judge Tomlinson said he was sympathetic to Jha but the case was "very complex" and took time to resolve.
