Roman Seleznev, a Russian man accused of hacking point-of-sale systems, was ordered to remain in federal custody this past week until his scheduled October trial.

Seleznev’s attorneys requested he be released on a $1 million bond secured by $100,000 in cash, but a U.S. judge rejected the plea after determining he was at a flight risk and has money in bank accounts around the world, according to a Department of Justice release.

Although Seleznev would have been put on house arrest and ordered to have electronic home monitoring installed, along with no access to computers, Magistrate Judge James P. Donohue thought he could still potentially create false documents to travel.

Seleznev, the son of Russian lawmaker Valery Seleznyov, allegedly stole and sold credit card numbers from Washington, D.C. area restaurants.
