Thaksin's assets frozen
 
Meanwhile in the capital, Bangkok, 780km north of Yala, a state anti-graft body announced that it would freeze an additional $63m in assets believed to be controlled by Thaksin Shinawatra, the ousted prime minister who has been accused of corruption.
 
The latest order to freeze the assets of Thaksin and his family would bring to more than $2.1bn frozen on suspicion that the money was obtained through corrupt means, said Sak Korseangruang, spokesman for the state Assets Examination Commission.
 
It was previously reported that more than $2.5bn in assets had been frozen but Sak explained that some money had been counted twice because of confusion over money sought and money actually found.
 
The assets frozen Monday are in bank accounts, mutual funds and other financial instruments mostly under the name of Thaksin's wife Pojamarn.
 
Since the middle of last month, the commission established after a September coup that deposed Thaksin - has been freezing assets belonging to him and his family pending the outcome of court cases related to charges of corruption and abuse of power.
 
If the courts rule against Thaksin, the money could be seized by the government.
 
Thaksin has denied any wrongdoing and accused the military-appointed government that succeeded him of persecuting him for political reasons.
 
Thaksin became a billionaire in the telecommunications sector before entering politics and serving as prime minister between 2001 and 2006.
