Watcharapol said the inquiry was at an initial stage and the NACC has been doing its best to look into all aspects of the issue. He said the NACC has procedures to follow, and its secretary-general has already reported twice to commissioners about the case.
As Prawit has been seen wearing more than 20 luxury watches on different occasions, the NACC would need to find out more details, Watcharapol said.
Prawit, he added, had not yet reported anything in addition to his initial letter of explanation to the NACC.
