Wirecard and its fugitive former No. 2 executive played a key role in an alleged scheme to trick banks into processing marijuana sales, according to evidence and testimony at the New York trial of two businessmen charged with orchestrating the plan.

Federal prosecutors in Manhattan say Wirecard was one of several European banks that opened fraudulent accounts to disguise around $160m in marijuana purchases made through Eaze Technologies, a California-based marijuana-delivery service. During a trial this month, witnesses have testified that Wirecard’s former chief operating officer, Jan Marsalek, was deeply involved in the alleged scheme.
