A US Virgin Islands investigations into the sex trafficker Jeffrey Epstein's ties to an American bank issued subpoenas to four wealthy business leaders on Friday, extending its reach into the highest echelons of tech, hospitality and finance. The subpoenas issued to the Google co-founder Sergey Brin, Hyatt Hotels chairperson Thomas Pritzker, American-Canadian businessman Mortimer Zuckerman and former CAA talent agency chairperson Michael Ovitz are crafted to gather more information about Epstein's relationship with JPMorgan Chase. The Virgin Islands' lawsuit against JP Morgan, the world's largest bank in terms of assets, alleges that the institution "facilitated and concealed wire and cash transactions that raised suspicion of " and were in fact part of " a criminal enterprise whose currency was the sexual servitude of dozens of women and girls in and beyond the Virgin Islands". "Human trafficking was the principal business of the accounts Epstein maintained at JP Morgan," it said. The disgraced financier ... owned two private islands " Little Saint James, or "Epstein Island", and Great Saint James " in the American territory, and authorities there have secured a $105m settlement from his estate. The demand for any communications and documents related to the bank and Epstein from four of the wealthiest people in the US comes days after it was reported that Jamie Dimon, JP Morgan's chairperson and chief executive, is expected to be deposed in the case.
