Nov 24 (Reuters) - Women who have accused Jeffrey Epstein of sexual abuse filed lawsuits against Deutsche Bank AG (DBKGn.DE) and JPMorgan Chase & Co (JPM.N) on Thursday, alleging the banks financially benefited from the late financier's alleged sex trafficking operations.His longtime associate, British socialite Ghislaine Maxwell, was sentenced to 20 years in prison for helping to recruit and groom underage girls over the course of at least a decade, filing an appeal in July.In the lawsuits filed Thursday, the plaintiffs accuse the banks of "providing the requisite financial support for the continued operation of Epstein’s international sex trafficking organization" in violation of the Racketeer Influenced and Corrupt Organizations Act (RICO), a U.S. law used to target illegal conspiracies that originally was designed to target organized crime."Epstein’s sex-trafficking venture was not possible without the assistance and complicity of a financial institution—specifically, a banking institution—which provided his operation with an appearance of legitimacy and special treatment to the sex-trafficking venture, thereby ensuring its continued operation and sexual abuse and sex-trafficking of young women and girls," lawyers for the anonymous plaintiff wrote in the Deutsche Bank lawsuit.The filings come as New York on Thursday opened up a one-year period allowing adult sex abuse victims to file cases that previously would have been too old to be considered in court."
