The four suspects were arrested in Pattaya Thursday night and were handed over to the Wang Thong Lang police station where they were detained for questioning. 
Police declined to give information about the four suspects but three of them were identified by sources as Arti, Ah-xing and Jeyi. 
The sources said the four were among seven Myanmar workers at the restaurant who took part in the killing of Chen Yi Hai at the restaurant in the Town-in-Town area in Wang Thong Lang district early Thursday. 
Police said CCTV footage showed that seven staff members had left the restaurant at around 3am. The body of the victim was found later that morning. 
Police found Bt19,000 in cash at the site of the murder and quoted Chen’s relatives as saying that he was ready to take the restaurant over from the Thai owner, identified only as Wiroj. 
Chen had reportedly started visiting the premises and had staying there since August 20. 
Police said the seven were angry after Chen reprimanded them for making noise while drinking.\
