A former iSentia executive was arrested in Thailand on corporate tax evasion charges two months after the major media monitoring provider signed a lucrative contract with the Australian Taxation Office.

Thai police arrested the former Asia chief executive of iSentia, David Liu, in June over suspected tax evasion of up to 5.2 million baht ($246,000). He denied wrongdoing, the Bangkok Post reported. iSentia says the proceedings are “without foundation” and it is confident they will be dismissed.
