Provincial police acting chief Pol Colonel Sarayuth Sa-nguanphokhaisaid said police were gathering evidence and investigating a claim that CCTV cameras at Malin Sky pub – which has since been closed – were broken and had been removed for repair.
Sarayuth, who had a meeting with Chang Puak police yesterday, said officers had interviewed 16 witnesses to the incident. As well as Kritsana, other celebrities and customers would be called to testify.
Kritsana was accused of ordering the assault on Issarajnuwat Wakkawisan, 23, but Lakana told the press that, although the couple were in the pub that night, they were not involved in the incident.

Unknown number of suspects
Sarayuth said one of the guards who was arrested earlier and had confessed to assaulting the victim alone would be interrogated further. He said police had not yet concluded how many people were involved in the brawl and would proceed according to the law to ensure justice.
Issarajnuwat, a fourth-year student at Payap University and son of 38th Army Circle commander Maj-General Witthaya Wakkawisan, suffered a broken nose, two cracked teeth, a fractured jaw and a bruised left eye in the incident. He is being treated at Lanna Hospital.
Deputy Prime Minister General Prawit Wongsuwan said yesterday police would investigate the assault and check if the pub, which is close to a university, could be allowed to continue to operate.
Prawit said he was in charge of police affairs and officers should perform their duties without fear of any outside influence.
