Authorities now say two bombs, including one that exploded on a Bangkok bridge the day after the shrine blast, were set off by Mr Karadag and Mieraili Yusufu, the only other suspect in custody. Mr Yusufu, who is allegedly from the Xinjiang region of China where many Uighurs live, is accused of detonating the shrine device after Mr Karadag planted it. Both men allegedly confessed after interrogation by the military junta.
