A campaigner for indigenous rights is being questioned by police in connection with the kidnapping of timber workers in Irian Jaya province last month. Tom Beanal, head of the Amungme Council in Timika, was interrogated for several hours this week and must report his movements to police pending further questioning. About 50 tribesmen snatched 16 employees of the Djajanti Group from their base camp on August 14. The camp lies 60 kilometres north of the mining town of Timika in southern Irian Jaya. Most of the hostages have been released but troops, backed by special forces units, are still trying to rescue at least three employees. The tribesmen have demanded an end to logging on their territory, mediation by human rights groups and the appointment of Mr Beanal as chief negotiator. The military sparked controversy last month when it accused Indonesia's leading environmental group, Walhi, of being one of several non-governmental organisations suspected of involvement in the kidnapping. Mr Beanal is a member of the national council of Walhi, which is partly funded by the United States Agency for International Development. The military later withdrew the allegations. It has since accused the kidnappers of being separatists. Mr Beanal was unavailable for comment yesterday but Walhi chairman Enny Hafild revealed police said they had at least two letters from the kidnappers implicating Mr Beanal in the kidnapping. Meanwhile, lawyers for ousted opposition leader Megawati Sukarnoputri say judges have adjourned for three weeks a court case she is bringing against the Government and military. A member of Ms Megawati's legal team, Luhut Pangaribuan, said the delay was to allow the defendants time to consider the charges. Ms Megawati is suing the authorities for allegedly supporting a rebel party congress in June which led to her ousting. Her lawyers yesterday sought a court order to stop the rival faction seizing party assets. Mr Pangaribuan, also a director of the Legal Aid Foundation, said the attorney general's office also questioned Budiman Sudjatmiko yesterday. He is accused of helping incite riots on July 27, which followed the eviction of Ms Megawati's supporters from party headquarters. Ms Megawati will be questioned by the attorney-general's office on Tuesday as a witness in the case, it was announced yesterday. Police have questioned her twice already.
