The right-hand man of deposed government leader Aung San Suu Kyi was arrested on Friday, days after the Myanmar army seized power and arrested Suu Kyi.

Win Htein, 79, was arrested at his daughter’s home around midnight, a spokesman for the National League for Democracy, which Htein and Suu Kyi belong.

Just before his arrest, Htein had responded to the coup by saying that “everyone in the country should resist as much as possible the actions they are trying to destroy our government”.

In Yangon, loud protests against the military coup were held for the third night in a row. People were beating pots and pans, and drivers used their car horns to make a noise.

The army arrested Nobel laureate Aung San Suu Kyi on Monday and seized power in the country. According to the Assistance Association for Political Prisoners, 130 bureaucrats and lawmakers have been detained since the coup. The military rulers have meanwhile put Facebook on black. Opposition supporters used that service to criticize the coup plotters.

The UN Security Council on Thursday called on the military regime to immediately release all prisoners, including the deposed head of government. US President Joe Biden echoed that call later in the day.
