Media firebrand Chuvit Kamolvisit is calling on the national police chief to take immediate action against two senior police officers accused of being behind a large online gambling network.

Mr Chuvit spoke following a police crackdown on gambling site macau888. The case was triggered by a string of allegations by TV actress Arisara Thongborisut.

She alleged that the macau888 network was operated by four brothers, including her ex-boyfriend "Benz Daemon". Police have so far arrested 46 suspects and seized many assets.

Mr Chuvit said the macau888 network, which had about 5.5 billion baht in circulation, was relatively small compared to another gambling network run by "Inspector Sua" and "General Jor". They used their connections to run the network with more than 10 billion baht in circulation, he said.

"Inspector Sua" is ex-cyber police who works in logistics but rarely shows up for work, he said, adding the national police chief must clean up cyber police units starting with "Inspector Sua".

"I give you until Monday, and if you take no action, don't blame me for any damage to the police force's reputation," the ex-massage parlour boss said, adding while physical gambling dens pay off police units to keep authorities looking the other way, gambling sites only deal with cyber police.

As for the macau888 network, he said cyber police waited too long before taking action, and the four brothers fled. The network allegedly asked "General Jor" to help in exchange for 500 million baht, he said.
