A 36-year-old woman who was arrested for pepper spraying a man at Takadanobaba Station train station in Tokyo last month has been sent to an institution by the Tokyo District Court.

The court made the ruling on Friday, saying that Yumiko Tsukakoshi, who lives in Nerima Ward, is not mentally fit to stand trial but that she should be committed to an institution because she poses a danger to others, Fuji TV reported.

Tsukakoshi was arrested on assault charges after she used pepper spray to injure nine passengers, aged 13 to 42, on the platform of the Seibu Shinjuku Line at around 5:30 p.m. on Sept 28. All nine were taken to hospital.

Police said Tsukakoshi sprayed the can first at the neck of a 32-year-old man. Station surveillance camera footage led them to Tsukakoshi. A can of pepper spray was found at her home.

Following her arrest, Tsukakoshi denied the charge and said she never went to Takadanobaba Station. Afterwards, she told police she had been “a victim of groping.” Tsukakoshi, who claims to work in the entertainment industry, said the man she sprayed looked like a man who had groped her on the train once before.
