TAIPEI, Taiwan — A man with at least one knife and smoke grenades attacked crowds indiscriminately in Taiwan’s capital on Friday evening, killing at least three people and injuring nine others, according to the national news agency and the city government. The suspect later fell to his death from a department store building.

Police said that the suspect was declared dead at a hospital after jumping from the building’s sixth floor, the Central News Agency reported.

The suspect, identified as a 27-year-old man named Chang Wen, threw smoke grenades near an underground exit of the Taipei Main metro station, close to the city’s main train station, and randomly attacked people with a “sharp object,” sending pedestrians running, according to media reports.

He then headed north to a popular shopping district, where he threw smoke grenades and stabbed multiple people on the first and fourth floors of the Eslite Spectrum Nanxi department store, primarily in the neck, the news agency said, citing police.

Police later revealed that the suspect, between the two scenes, took an underground path to a hotel, where he fetched some “lethal weapon” — or some kind of edged weapon — before showing up at a road outside the Zhongshan metro station, near the department store, according to the news agency.

Police said they were yet to find any accomplice and were investigating possible motives. Police said they recovered some “lethal weapons” in both the suspect’s rental home in Taipei and the hotel room where he had stayed for three nights near Zhongshan.
