The Myanmar authorities have taken an activist monk away from a monastery in Yangon, a fellow monk said Friday, only weeks after he was released from years of imprisonment.

U Gambira, who was freed by the government last month along with other political prisoners, was taken away early Friday by about 10 men in plain clothes who said they were from the "Yangon Division," said U Thika, a monk who witnessed the events.

The men who took U Gambira away did not give details on where they were taking him or why, U Thika said. He added that the men said that they were not arresting U Gambira but wanted to talk to him.

The move comes after the Myanmar government has taken notable steps to improve its human rights record.
