FEARS were expressed last night for the safety of dozens of pro-East Timor activists who were in Indonesian police custody after demonstrations at embassies in Jakarta. A spokesman for the People's Democratic Union said there was growing concern for 58 people who were taken to police headquarters from the Russian mission after being assured of safe passage to the nearby Legal Aid Foundation. 'The chief of intelligence is still interrogating those people in a room,' an official at the headquarters said three hours after the protesters left the embassy. Lawyers from the Legal Aid Institute were refused access to the protesters. The group left the embassy in a government bus, reportedly with eight policemen and prominent human rights campaigner Johannes Princen on board. Mr Princen played a central role in negotiations on their safe passage out of the embassy. To shouts of 'traitors' and 'dogs', the demonstrators and their sympathisers at the Russian Embassy were driven away, witnesses said. Onlookers hurled stones at the protesters, who resent Indonesian rule of their remote territory. Mr Princen said he was surprised the demonstrators were taken to police headquarters because the original plan with police was to go the institute. He said an official at the institute had told him police had guaranteed they would be freed after questioning. But student groups and Amnesty International said even if they were released unharmed there was concern about future intimidation. Attempts to contact another 20 already in custody at Jakarta's Polres police station had had little success, an activist said. They were arrested on Thursday while trying to enter the French and Thai embassies. 'We have not been able to meet them, nor has a lawyer from the institute,' Beathor Syradi, of the pro-democracy group Pijar, said. 'Amnesty International is concerned for their safety, in view of the fact that those who seek to draw attention to the situation in East Timor are frequently at risk of arbitrary arrest, and in many cases torture.' Sources close to a 55-member group of East Timorese in the Dutch Embassy said there were no plans for them to leave soon. 'They have not yet decided what to do but they are still sticking to their demands, including for a referendum in East Timor,' one source said. The protesters broke into the Dutch and Russian embassies before dawn on Thursday, the 20th anniversary of Indonesia's invasion of the former Portuguese colony of East Timor. Sources close to the protesters said the original plan was for the East Timorese in the two groups to stay for 20 days, while the other Indonesians would stay for five days. Other embassies were on alert yesterday for more possible break-ins by Timorese protesters, as well as protests by members of a pro-Indonesian group who injured four Dutch diplomats on Thursday after forcibly entering their embassy. However, Mr Syradi said ethnic East Timorese activists stood a good chance of being released without charges. Meanwhile, about 60 activists held a demonstration in the grounds of East Timor's Dili cathedral yesterday. They chanted 'Viva Xanana' and 'long live East Timor'. Xanana Gusmao is the jailed leader of the East Timor resistance movement.
