YANGON, Myanmar (AP) — Thein Zaw, a journalist for The Associated Press, has been released from detention in Myanmar. He was arrested more than three weeks ago while covering a protest against the coup. He waved and smiled to photographers as he left Yangon’s Insein Prison on Wednesday. Thein Zaw told the AP by phone that the judge in his case had announced that all charges against him were being dropped because he was doing his job at the time of his arrest. He was one of nine media workers taken into custody during a Feb. 27 street protest in Yangon, the country’s largest city, and had been held without bail. About 40 journalists have been detained or charged since the Feb. 1 coup.
