TAIPEI (Taiwan News) — The Taipei District Prosecutor's Office said Friday that four former military personnel have been indicted on charges of breaking the National Security Act and selling state secrets to China.

Among those indicted, three were members of Military Police Battalion 211, which is responsible for securing the Office of the President, while the fourth was part of the Ministry of Defense’s electronic warfare unit, per CNA. Prosecutors said the individuals were paid for information.

The total payment received by the four ex-military personnel was NT$1.84 million (US$55,607), with the amount depending on the sensitivity of the intelligence. The case was initially flagged by the defense ministry through its internal reporting mechanisms.

After conducting a preliminary investigation, military police asked prosecutors to take over the case. The four individuals have confessed to the charges and the authorities are also seeking a suspected spy surnamed Huang (黃), who is believed to have been responsible for relaying the information to China.

The defense ministry condemned the actions of the four individuals. Office of the President Speaker Lii Wen (李問) also condemned the treasonous actions of the accused and added the case would be monitored, per SETN.

Lii said traitors should face the harshest legal consequences. He also pointed at enhanced counter-espionage training to strengthen Taiwan's resilience.
