A 30-year-old Vietnamese man who was thought to be ill on Saturday night was approached by police officers from Taichung, Taiwan. They later arrested him for abusing an illicit substance and overstaying his visa for more than three years.

On January 12, two officers surnamed Wang and Chen from Jizhong precinct of the Taichung City Police Bureau found a man sitting alone with a blank expression at the intersection of Chenggong Road and Jiguang Street, the United Daily News reported.

The officers approached the man to see if he needed help. However, while checking the Vietnamese man’s name and passport, there were discrepancies in the information he gave them. The officers then discovered that the man they were talking to had abused a compatriot’s identity, and overstayed in Taiwan for more than three years.

Around NT$100,000 (US$3,200) in cash and five sachets of amphetamine were recovered from the pockets of the man’s jacket. He insisted that these were his savings from working illegally, and which he was intending to send home.

Preliminary investigations found that the man was drowsy from abusing the illicit substance, which he claimed was for self-consumption only.

He was arrested for violating the Narcotics Endangerment Prevention Act and illegal overstaying.
