Chen and Wu were arrested in Taiwan along with 300 other members of the Bamboo Union during a 13 November 1984 government crackdown on organized crime. Chen reportedly confessed to his and Wang's roles while imprisoned, and two days later, on 15 January 1985, the three officials named in the confession were relieved of their duties and placed under arrest. At that time, an investigation by the FBI and Daly City police surfaced; they had been quietly questioning Los Angeles-area Bamboo Union members, seeking a copy of Chen's October recording. The government of Taiwan continued to deny culpability in the death of Liu, claiming that Wang and his subordinates were not acting as agents of the Taiwanese government. The existence of the tape-recorded October confession remained a rumor until the "Los Angeles Times" obtained a copy of the recording in March 1985 from Chang An-lo, a friend of Tung who had hosted him in September 1984.
