A former National Security Agency contractor will be charged with violating the Espionage Act after he allegedly stole an “astonishing amount” of highly classified information over 20 years, federal prosecutors said Thursday.

Authorities said Harold Thomas Martin III took at least 50 terabytes of data, “six full banker’s boxes worth of documents,” and personal information about government employees, according to the Washington Post.

Earlier this month, the Justice Department announced a criminal complaint against the 51-year-old Maryland man. He is expected to appear at a detention hearing Friday in U.S. District Court in Baltimore, where prosecutors plan to argue against his release from jail.
