A man arrested following a knife attack on a Tokyo train on Halloween night was served a fresh arrest warrant Monday on suspicion of attempted murder and arson, investigative sources said.
Kyota Hattori, 25, who wore a costume resembling that of the Batman villain the Joker during the attack, is suspected of trying to kill passengers including a 60-year-old woman by sprinkling approximately 3 liters of oil around the train and igniting it, the sources said.
The police quoted Hattori as saying, "I executed a plan to kill many people in an effective and efficient manner so that I will get the death penalty."
