A 27-year-old man went on a stabbing spree in Taipei’s metro system, injuring four people in an attack that brought to mind last year’s MRT attack that left four dead and 24 wounded. The suspect, Hsu Li-min, was apprehended at the scene and explained that his actions resulted from his chronic joblessness and “bad mood.” None of the victims was critically injured and all received treatment in area hospitals. Police patrols of the metro system were increased following the incident. Taipei City Mayor Ko Wen-je, noting the similarities between the recent attack and last year’s fatal mass stabbing, called for increased attention to public mental health. Cheng Chieh, the perpetrator of last year’s attack, has been sentenced to death.
