Stabbing sprees at train stations have been making headlines in recent months.
Last week, college student Cheng Chieh sparked panic among commuters when he executed his planned knife attack on board a Taipei subway train.
The 21-year-old, who had dreamed about the attack for years, said it felt “nice” after stabbing four people to death.
The unprecedented attack, which has even spurred copycat threats in Taiwan, is the latest in a spate of train station stabbings. Here's a look back at stabbing sprees that made headlines.
