Under cover of darkness, the soldiers rolled up outside a school building on the outskirts of Myanmar's main city, Yangon. It was 1.30am. The military began searching the Suu Vocational College, in the north-west suburb of Shwe Pyi Thar. They moved swiftly from room to room.

They had come to arrest Zaw Myat Lynn, a prominent community organiser and teacher. He was an activist with the National League for Democracy (NLD), the party of Aung San Suu Kyi. In November, the NLD won a landslide election victory. It was in power until last month, when the military abruptly ended civilian rule.
