SEATTLE (AP) — A federal prosecutor asked a judge to deny requests for changes in the custody of a Russian man charged with hacking into U.S. businesses, arguing his lawyers have illegally given him access to a cellphone and mail.

Roman Seleznev was indicted in 2011 on charges that he stole thousands of credit card numbers from businesses and restaurants across the U.S. He was arrested in Maldives in July and flown to Guam and then Seattle. Seleznev, the son of a prominent Russian lawmaker, has pleaded not guilty.
