Petaling Jaya – Three Malaysians were queried by Jakarta police Thursday for suspected participation in a demonstration at the Indonesian capital, where the 18th Asean Summit is being held this weekend.

The three were Sisters-in-Islam member Nazreen Nizam, Parti Sosialis Malaysia (PSM) member Choo Chon Kai and Enalini Devi Elumalai of human rights group Suaram.

The trio were reportedly held for questioning at the Polda Metro Jaya police station for about three hours. It is believed that they were in Jakarta to participate in the Asean Peoples' Forum.

In the incident, an Indonesian group known as Solidarity Indonesia For Asean People held a one-hour demonstration in front of the Asean secretariat office, carrying posters and a petition letter.

When contacted Friday, PSM secretary-general S. Arutchelvan said the three were merely watching the demonstration from afar. "I was in contact with one of them via SMS and was told that they were not arrested by the police but merely called in for an enquiry," Arutchelvan said.

Indonesian news portal detikcom said the three were seen leaving the police station at about 8.30pm (Jakarta time) Thursday.
