Sondhi Limthongkul has taken Prime Minister Abhisit Vejjajiva to task for failing to dismiss national police chief Patcharawat Wongsuwon.

Mr Sondhi's People's Alliance for Democracy blames Pol Gen Patcharawat for the slow progress in the investigation into the attempted murder of Mr Sondhi on April 17.

Mr Sondhi yesterday told reporters that if the police could not arrest a suspect in the attempted murder of a person of his profile, the nation might be in trouble.

He said Mr Abhisit and other people in important positions could also become assassination targets.

The PAD leader criticised Mr Abhisit for lacking the maturity of a leader by failing to remove Pol Gen Patcharawat as police chief.
