Piti Bhirombhakdi, regional marketing director of Boon Rawd Brewery, and actress Virithipa "Woonsen" Phakdeeprasong yesterday had their representatives provide information on their behalf to the Alcoholic Beverages Committee, in relation to celebrities posting photographs with alcoholic beverages on social media.
Six more celebrities will visit the panel next Thursday and two more the following day.
Dr Samarn Futrakul, director of the committee, said he would also invite Pakorn "Dome" Lam, Hansa "Newclear" Jungviwattanawon and Napasasi "Mind" Surawan, as well as their managers to provide an explanation early next month.
If the managers were found to be involved in the posting of these photos, they will be punished, he said.
He added that representatives of the product manufacturers would also be asked to provide information.
Piti, who posted comments criticising the posts, was not a witness or plaintiff and he only expressed his personal opinion over a matter that should be handled by state officials, Piti's representative Boon Rawd exec Chatchai Wiratyosin said.
Meanwhile, Virithipa's lawyer Nitithorn Kaewto claimed the actress was busy and would provide an explanation in person later.
