The national police chief has ordered cybercrime suppression police to travel to Taiwan to seek more information from a Thai actress about the macau888 online gambling network.

Actress Arisara "Due" Thongborisut on Wednesday evening posted a video clip on her Facebook page, accusing her ex-boyfriend Chaiwat "Benz Demon" Kachornboonthaworn of being one of the "four brothers" allegedly running the macau888 gambling operation.

Ms Arisara also accused Mr Chaiwat of physical assault.

Police will send a team of officers to question the actress in Taiwan, according to a source.  

The crackdown operation on macau888 network members came after the 32-year-old actress shed light on the operation and those involved on her Facebook page on Jan 15. In her post, she provided clues that the gambling network was allegedly run by the "four brothers", all with the initial “Bor”.

The four siblings left Thailand for Hong Kong on Jan 16, according to police.

In Ms Arisara's post on Wednesday, the actress spoke in tears that she had been physically and mentally abused for almost two years by her ex-boyfriend. In one incident, she accused him of pouring a bowl of hot noodles onto her head in the presence of other people in his family. Nobody came to her rescue, she said tearfully. She showed pictures on her mobile phone of wounds.

Police have so far arrested 46 suspects and seized a large amount of assets in their investigation of the macau888 network.

The latest details were released after the youngest brother of the prime suspect in the case was released from detention on Tuesday night after taking unapproved leave to accompany the fugitive to Hong Kong. The youngest brother is a police immigration inspector. Three people were arrested in the initial raids.

Police said 12 suspects were still at large, and one of them was Mr Chaiwat, who reportedly postponed his planned surrender on Wednesday.
