Jim Della-Giacoma, Jakarta – Indonesia moved to deport a U.S. woman on Thursday after police accused her of "disturbing public order" during a ceremony marking the anniversary of a 1991 massacre of East Timor civilians by Indonesian soldiers.

An immigration official in the territory's capital, Dili, said Lynn Anne Fredriksson, 34, was expelled from East Timor on Thursday morning. She was put on a flight to the resort island of Bali.

"There is indeed an American woman here in the waiting room accompanied by American consulate officials. She was earlier sent from Dili," Yunus, an immigration duty officer at Bali's Ngurah Rai airport, told Reuters by telephone.

"She will fly to Singapore this afternoon at 5 p.m. (0900 GMT) on a Singapore Airlines flight," he said.

The official Antara news agency quoted the head of the Justice Department's East Timor office, I Made Parke, as saying that Fredriksson was expelled for violating immigration laws by disturbing security and public order during Wednesday's ceremony.

It had earlier quoted East Timor Police Chief Colonel Atok Rismanto as saying Fredriksson was being deported because she abused her tourist visa by undertaking "journalistic activities."

Parke said Fredriksson was a freelance writer specialising in human rights and had violated immigration laws as she had entered the country on a tourist visa. Her friends in the United States said she was not a journalist.

Fredriksson was not available for comment and the U.S. embassy in Jakarta said they were unable to comment on the case.

Parke said Fredriksson's diary contained the names and addresses of a number of "problematic" Indonesian non-government organisations which had discredited Indonesia.

Based upon this evidence, it was suspected she was a danger to public order under section 42 of the 1992 immigration law.

"Lynn Ann is being deported from Indonesia because it has been proved she has broken the law. We are proposing her name be entered on the black which means she will be forbidden from entering Indonesia," Parke was quoted as saying. Rismanto said Fredriksson engaged in journalistic activities an hour before the University of East Timor held a candlelight vigil for protesters killed near Dili's Santa Cruz cemetery in 1991.

The government has said that Indonesian troops killed 50 demonstrators on November 12, 1991, following a funeral for anti-Indonesian activists.

Witnesses and human rights groups estimated more than 180 people died in the 1991 incident.

Indonesia invaded the former Portuguese colony of East Timor in December 1975 and incorporated it as its 27th province the following July in a move the United Nations has refused to recognise.

Rismanto said Fredriksson had given the students support and encouragement. He said she had taken pictures of the students' activities, in violation of her tourist visa.

Police said earlier they had seized her film and developed it.

East Timor police spokesman Captain Widodo said from Dili on Thursday Fredriksson was the only person detained at the candle lighting ceremony.

Rismanto said that during an interrogation by policewomen, Fredriksson ate a piece of paper which police believed contained information that she did not want to fall in the hands of authorities.
