U.S. prosecutors allege a man with multiple aliases used the name of the famed Astor family to scam a Mexican billionaire out of $450 million. According to a New York federal grant jury indictment unsealed Monday, Vladimir Sklarov set up a fake company called Astor Asset Group and claimed it was linked to the wealthy New York Astor family to gain credibility. Sklarov was arrested in Chicago on Saturday. The alleged victim, Ricardo Salinas Pliego, confirmed he was a victim in an interview with The Wall Street Journal. The indictment alleges Sklarov illegally sold $450 million worth of corporate shares that Salinas had put up as collateral for a loan. A lawyer for Sklarov did not immediately return messages.
