The son of ousted Thai premier Thaksin Shinawatra has more than doubled the reward offered by police for the capture of those behind the bombing in Bangkok on Monday. He has put up nearly US$200,000 (S$281,000).
The attack on the Erawan shrine killed 20 people, sending shock waves through the nation's vital tourism sector.
Police have offered a three million baht (S$118,500) reward for any information that leads to the capture of the assailant.
That offer has now been more than doubled by Mr Panthongtae Shinawatra, the first-born son of the former populist leader. Mr Thaksin lives abroad in self-imposed exile after a corruption conviction that he insists was political.
