Chiang Mai – In yet another example of the junta's continuing brutal crackdown on dissidents, sources say Burmese authorities on Tuesday arrested two more Burmese opposition members.

Tin Myint and Tun Aung, both members of Burma's main opposition party National League for Democracy, remain in custody since being taken for interrogation on Tuesday night by Special Branch Police, a NLD youth member told Mizzima.

The NLD youth said Special Branch Police detained Tin Myint, chairman of the Thingankyun Township NLD, and Tun Aung, a youth member of the Thingankyun NLD, at about 11:00 p.m. (local time).

"Both of them have not returned home. We don't know who the police were; they just said they were on duty. We still don't know where the two of them are being kept," the NLD youth added.

Burmese authorities commonly fail to inform family members of the whereabouts of those taken for interrogation, leaving relatives alone to contemplate the fate of loved ones.

Similarly, on March 30, several NLD members including Aung Than Tun, Aung Kyaw, Ye Zaw Htike, Tin Oo Maung and Khin Soe were reportedly arrested in Rangoon.

On Monday, Amnesty International condemned Burma's ruling junta for arresting and sentencing activists involved in last year's August and September protests.

Amnesty International reported that the government has conducted at least forty secret trials of protestors inside prisons.
