Chiang Mai - Burmese military junta authorities on Monday released 70 year old Tin Tin Win, mother of a student activist, after detaining her for four days.

Tin Tin Win, mother of 88 generation student Ant Bwe Kyaw, was arrested by the police on Thursday from her residence in Yan Kin Township, Rangoon.

"She was interrogated. She did not say anything and she requested not to be called even over telephone," said Daw Kyi Oo, a friend of Tin Tin Win and mother of the detained popular comedian Zarganar.

While the reason for the brief detention of Tin Tin Win, it is still unclear political activists believe there could be a connection with the visit paid to her by a woman activist Nilar Thein, who was also arrested on the same day.
