>>TOKYO, April 10 (Kyodo) -- Police confiscated Friday several thousand
>>cassette tapes, believed to contain recordings of police digital radio
>>communications, from a radical group's hideout in Urayasu, Chiba
>>Prefecture, east of Tokyo.
>> Investigation sources said the Metropolitan Police Department (MPD)
>>will examine the tapes to determine when Kakumaruha (Revolutionary
>>Marxist Faction) intercepted digital radio transmissions and how they
>>used the decoded information.
>> Eight female members at the group's apartment during the raids are
>>being questioned on their involvement in the wiretapping operations.
>>Digital radio can only be deciphered by computer experts.
>> The MPD began the raid Thursday based on its findings from a raid on a
>>hideout in Tokyo in January when they confiscated a memo apparently
>>based on police radio conversations.
>> By the time investigators completed their search Friday morning,
>>assorted radio equipment and documents enough to fill some 80 cardboard
>>boxes had been confiscated.
>> Police believe the group used the radios to pick up digital radio
>>transmissions on a special police band which they were able to follow
>>even after the channels were changed.
>> In a news conference Thursday evening, Kakumaruha members provided
>>confidential details of an investigation on the shooting of then
>>National Police Agency chief Takaji Kunimatsu in March 1995, indicating
>>its capability to monitor police radio.
>> The police raid was also conducted to search for evidence of the
>>group's alleged break-in at a Kobe hospital and theft of depositions
>>taken from a 15-year-old Kobe boy who killed two children and assaulted
>>three others last year.
>> On Tuesday, police put on a nationwide wanted list six Kakumaruha
>>members on suspicion of sneaking into the hospital several times last
>>September and stealing the documents.
