Five more members of a sword collectors group were arrested Sunday in connection with a bomb threat at a deputy foreign minister's house in September and three shootings at an association of pro-Pyongyang residents in Niigata in July and other facilities.
The sword group's leader, Ichiro Murakami, 54, and five other members were arrested Friday and indicted over three shooting incidents at Aum Shinrikyo facilities in Tokyo and Osaka, and a teachers union office in Hiroshima.
Investigative sources on Saturday quoted Murakami as admitting that he led the three shootings.
