A U.S. Navy officer has been charged with supplying a foreign nation with state secrets relating to America’s national security.

The Navy charge sheet that details the spying allegations has been heavily redacted, blacking out the suspect’s identity and other details.

Reuters and the U.S. Naval Institute identified the accused as Lt. Cmdr. Edward Lin. NBC News was not immediately able to verify those reports.

Lin was born in Taiwan and came to the U.S. aged 14 before becoming a naturalized U.S. citizen in 2008, according to an interview on the Navy’s official website.
