Kostin, who was sanctioned by the United States in 2018, is accused of money laundering and sanctions violations through his maintenance of two yachts and a home in the resort town of Aspen, Colorado, according to an indictment in Manhattan federal court.

Two associates, Vadim Wolfson and Gannon Bond were arrested in the United States on charges of helping to take care of the Colorado property while concealing that Kostin owned it, U.S. Justice Department officials said.

Kostin, who is believed to be in Russia, remains at large.

The indictment was one of five criminal and civil actions the Justice Department unveiled on Thursday as part of an effort by U.S. authorities to crackdown on people with ties to the Kremlin.
