On June 3, the Metropolitan Police Department arrested former Aum Shinrikyo cult member Ms. Naoko Kikuchi, who was on the wanted list for her suspected involvement in the 1995 sarin attack on the Tokyo subway system. She was living in Sagamihara, Kanagawa Prefecture.

Her arrest followed the arrest of former Aum leader Mr. Makoto Hirata, who surrendered to the MPD on Dec. 31. Investigative sources on June 5 disclosed that Mr. Katsuya Takahashi, the last Aum fugitive on the run, likely lived in Kawasaki, Kanagawa Prefecture, until late last year and may still be there.

Given her minor role in the cult, it is unlikely that Ms. Kikuchi will reveal surprising facts. But many points remain unclear about the cult's crimes.
