There they found three Myanmar men with bullet wounds in a room on the second floor. They were rushed to Mahachai Hospital. 
Police have yet to identify the injured workers. 
Witnesses told police that the gunmen are two Thai men who fled in a pickup truck after the shooting. 
Witnesses said the three worked as porters at a fresh market in Mahachai. Their friends said they had a quarrel with a group of Thai men four days ago and one of the Myanmar workers was so badly beaten he had to be sent to hospital. 
Pol Lt Col Pongsiri Kengnok, deputy commander of the Mahachai police station, said police learned that one of the attackers is a pork vendor at the fresh market. Police would seek an arrest warrant against him soon, Pongsiri added.
