(Photo: AHRC) Phyo Wai Aung, the man accused of carrying out a deadly bombing during the Burmese water festival in 2010, has died just months after his release from prison from an illness that went untreated while he was still in custody. Family members said he died at his home in Rangoon’s Kyauk Myaung Township at around 3 am on Friday. The 33-year-old engineer was sentenced to death in May of last year for his alleged role in a series of bombings that killed at least 10 people and injured around 100 others during festivities to mark Thingyan, the Burmese new year, in April 2010. He was subsequently released under a presidential pardon on Aug. 3, 2012.
