Relatives of a Buddhist monk who led Burma's 2007 Saffron Revolution say he has been detained for questioning by authorities.

Ashin Gambiya's older brother, Aung Kyaw Kyaw, told VOA's Burmese service that Gambiya was arrested by members of Burma's military intelligence department (Special Branch) late Tuesday at his sister's home in Rangoon.

He says the two were scheduled to meet with the British ambassador on Wednesday.

Tate Naing, a spokesperson for the Thai-based Association for Assistance for Political Prisoners-Burma told VOA that they confirmed that Gambiya was taken away for questioning, but that he is expected to be released by Thursday.

The monk was previously sentenced to 68 years in prison for leading pro-democracy protests in 2007.

Burmese citizens began weeks of mass protests against the military in June 2007 before authorities crushed the demonstrations. The United Nations says at least 31 people were killed and thousands more were detained in the crackdown.
