Jerry Chun Shing Lee, aka Zhen Cheng Li, 53, a former Central Intelligence Agency (CIA) officer, was arrested last night on charges of unlawful retention of national defense information.

Dana J. Boente, Acting Assistant Attorney General for National Security and U.S. Attorney for the Eastern District of Virginia, and Andrew W. Vale, Assistant Director in Charge of the FBI’s Washington Field Office, made the announcement.

Lee was arrested after arriving at John F. Kennedy International Airport in Queens, New York. Lee is a naturalized U.S. citizen, currently residing in Hong Kong, China. According to court documents, Lee began working for the CIA as a case officer in 1994, maintained a Top Secret clearance and signed numerous non-disclosure agreements during his tenure at CIA.

According to court documents, in August 2012, Lee and his family left Hong Kong to return to the United States to live in northern Virginia. While traveling back to the United States, Lee and his family had hotel stays in Hawaii and Virginia. During each of the hotel stays, FBI agents conducted court-authorized searches of Lee’s room and luggage, and found that Lee was in unauthorized possession of materials relating to the national defense. Specifically, agents found two small books containing handwritten notes that contained classified information, including but not limited to, true names and phone numbers of assets and covert CIA employees, operational notes from asset meetings, operational meeting locations and locations of covert facilities.

Lee made his initial appearance this afternoon in the Eastern District of New York. He is charged with unlawful retention of national defense information and faces a maximum penalty of 10 years in prison, if convicted. The maximum statutory sentence is prescribed by Congress and is provided here for informational purposes. If convicted of any offense, the sentencing of the defendant will be determined by the court after considering the advisory Sentencing Guidelines and other statutory factors. A criminal complaint contains allegations that a defendant has committed a crime. Every defendant is presumed to be innocent until and unless proven guilty in court.

Assistant U.S. Attorney Neil Hammerstrom of the Eastern District of Virginia and Deputy Chief Elizabeth Cannon of the National Security Division’s Counterintelligence and Export Control Section are prosecuting the case.
