Military investigators on Monday filed for warrants to arrest two active officers for allegedly leaking confidential information, officials said. Civilian prosecutors are also seeking a warrant to detain a university professor who allegedly gave away military secrets she received from the officers.

According to military officials, an Army lieutenant colonel surnamed Lee and an unrelated Navy lieutenant commander also named Lee, both working for the Defense Acquisition Program Administration (DAPA), are suspected of having handed over military secrets to the professor in question, surnamed Park, who was once a DAPA executive.

Officials said Park was the immediate superior to the two officers at the state-run DAPA.

The two officers have reportedly denied the charges during an investigation by the Defense Security Command, the nation's top counter-intelligence unit.

"We will seek to take into custody the people whose allegations of identifying and leaking military secrets brought against them are so obvious," an official with the Defense Security Command said. "We will have a thorough investigation to uncover the truth in the case."

Prosecutors raided the professor's office last month and discovered 18 confidential military documents, including one titled "Plan for Medium-Term National Defense," which details the military's reinforcement plans for every five years. She allegedly leaked nine of the files in 2006, including one on the defense budget, according to officials.

From 2004 to 2006, Park was an aide to a lawmaker who served on the National Assembly's standing committee on national defense. Prosecutors are trying to determine if Park has leaked any more confidential information. She has reportedly admitted to storing the secret files, but denied giving them away to other individuals or agencies.

Separately, civilian prosecutors are now investigating another DAPA officer, an Air Force lieutenant colonel, on similar charges. (Yonhap)
