Six people in Tokyo were hospitalized, after they had complained about malaise due to a strong smell in the subway train. According to witnesses there was a smell of solvent or, perhaps, any other chemical substance, in the metro, reports the BBC. The incident took place at Takadanobaba station at about 18: 00. Local television broadcasts footages from the scene. It was not yet clear, whether people in the metro became victims of chemical poisoning or not. The incident raised concerns of the local residents in Tokyo. They remember the chemical attack in the subway in Tokyo in 1995, organized by the followers of the AUM Shinrikyo radical sect. About 6 thousand people were poisoned, 13 killed due to  sarin spread in the metro.
