A former Deutsche Bank trader has filed a $30 million malicious prosecution lawsuit against the financial institution, claiming he was scapegoated by the German bank and falsely implicated in criminal wrongdoing.

Gavin Campbell Black was convicted of wire fraud in 2018, with prosecutors claiming he rigged the bank’s Libor submission. But the U.S. Court of Appeals for the Second Circuit last year overturned the conviction and exonerated him, citing a lack of evidence.
