The only American suspect named in the largest known hack of Wall Street is negotiating his return to the U.S. from a detention cell in Russia, where he’s no longer welcome, people familiar with the talks said.

Bloomberg News reports that Joshua Aaron, a Maryland native who attended Florida State University, has been held at a facility for illegal immigrants outside Moscow since failing to show police a valid passport during a midnight check at his apartment above the Beverly Hills Diner near downtown in May, court records show.

He and two Israelis are suspected of perpetrating what U.S. Attorney Preet Bharara called “securities fraud on cyber steroids” from 2007 to mid-2015. They’re accused of stealing data on more than 100m customers from JPMorgan and other companies, using it in schemes such as stock manipulation that generated hundreds of millions of dollars in illicit gains.

Along the way, members of the ring tried to extract nonpublic information from financial corporations, processed payment information for fake pharmaceuticals and fake anti-virus software, falsified passports and took control of a New Jersey credit union, prosecutors say.
