(Reuters) -Alex Mashinsky, the founder and former CEO of bankrupt cryptocurrency lender Celsius Network, was arrested and charged with fraud, a U.S. prosecutor in New York said Thursday, while three federal regulatory agencies sued him and his company. Mashinsky, 57, was charged with seven criminal counts - including securities fraud, commodities fraud and wire fraud - while Celsius' former chief revenue officer, Roni Cohen-Pavon, was charged with four criminal counts, according to the indictment, which was unsealed on Thursday. Lawyers for Mashinsky and Celsius did not immediately respond to requests for comment, and Cohen-Pavon's attorney could not immediately be reached.
