A monk in Myanmar, also known as Burma, who was one of the leaders of anti-government protests in 2007, has been released after briefly being detained again by the authorities.
Shin Gambira's brother says the monk was taken from a monastery in Rangoon.
Officials say he was merely being questioned and was not charged.
Mr Gambira continued his criticism of the military backed government after he and 650 others were released as part of an amnesty last month.
He began re-opening monasteries the authorities had locked up following the 2007 protests.
The government in Myanmar has begun a series of reforms to encourage the lifting of sanctions imposed by the West, but the BBC reports Mr Gambira has expressed scepticism about the reforms.
