Protesters opened the gate of Maafushi Prison in Male where the 12 MPs including former President Mohamed Nasheed are detained on Saturday.
Protests are being held in Male as President Abdulla Yameen refused to follow Supreme Court's ruling to release key political prisoners and reinstate 12 MPs.
Supreme Court of the Maldives had ordered the immediate release of exiled former leader Mohamed Nasheed and eight others, terming their trials a violation of the constitution and international law.
Nasheed, jailed for 13 years in 2015 on terrorism charges, got political asylum in 2016 in the UK, where he was allowed to go for medical treatment". He has since been living in Sri Lanka.
''Absolute breakdown of law and order. The public is on the edge. I am very concerned as we are facing increased unrest. They have just used pepper spray & tear gas on crowd,'' Eva Abdulla, Member of Parliament said.
