Authorities in Burma detained and then freed 15 activities who are seeking the release of pro-democracy leader Aung San Suu Kyi.
The activists were arrested Wednesday after they held a prayer vigil for Aung San Suu Kyi in the former capital, Rangoon.
In recent days about 50 activists have been arrested in different areas of Rangoon.
The pro-democracy leader's most recent house arrest is scheduled for review on May 27th.
A representative Debbie Stothardt from the human rights group, Alternative ASEAN Network says the arrests highlight the fear Burma's military junta has for any opposition.
Aung San Suu Kyi has spent most of the past 17 years under house arrest.
Separately, Burma has refused to renew the registrations of 24 civil organizations, including the Free Funeral Services Society.
The reason for the decision is not clear.
