Taiwan attacker planned assault that killed 3 and injured 11, authorities say

Taiwanese authorities said on Saturday (December 20, 2025) the suspect who killed three people and injured 11 others in knife and smoke grenade attacks in the island’s capital had planned the assaults and set fires at two other locations earlier in the day.

The suspect, identified as a 27-year-old man named Chang Wen, fell to his death from a department store building in Taipei after the attack on Friday (December 19, 2025).

The assaults shocked Taiwan, where violent crime is rare, prompting authorities to step up security at crowded spots and big events, including its New Year’s Eve celebration that usually attracts many locals and tourists to an outdoor countdown.

Chang Jung-Hsin, director-general of the National Police Agency, said the suspect began a series of attacks at 3:40 p.m. local time, first setting fire to roads and causing damage to cars and motorbikes. He also set fire to where he lived.

The suspect later threw smoke grenades near two exits of the Taipei Main metro station and used a knife to fatally wound a person, Mr. Chang said. After the attack, the suspect took an underground path to return to the hotel where he was staying. Then, he threw more smoke grenades and used his knife to kill another person outside the Eslite Spectrum Nanxi department store, the official said.

He also fatally wounded another person on the fourth floor of the department store building before he jumped from a male bathroom on the fifth floor to his death, Mr. Chang said.
