A man from Hsichih, Taipei County, was questioned late Thursday night on suspicions of spying for the Chinese military. He was released hours later on NT$30,000 bail.
The man, surnamed Tai, is alleged to have collected military intelligence since August, including taking pictures of the Hengshan Command Headquarters, and having sent it to China, officials from the Investigation Bureau under the Ministry of Justice said.
The Hengshan Command Headquarters is one of the most secretive and important military bases in Taiwan.
According to the investigators, Tai, in his 40s, mailed at least two parcels of military information, including hand-drawn pictures of Hengshan Command Headquarters' layout and terrain, to Chinese military and public security authorities.
The parcels were even directed to former Chinese President Jiang Zemin (
During questioning, Tai admitted that he had collected information on the Hengshan Command Headquarters and sent it to Chinese authorities out of indignation with Taiwan's tumultuous politics.
He denied, however, that any of the information he had sent was "military intelligence." He also accused the investigators of physically abusing him and asked to be sent to the hospital to get documented proof that he had been abused.
Prosecutors from the Shilin District Prosecutors' Office released Tai early yesterday morning after the questioning, deciding to conduct further investigations into the case before determining what crime to charge him with.
