He injured two female employees of the firm during the getaway, pistol-whipping one in the face and wounding another with a knife, police added.
Lumpini police say Wanchai claims he was owed nearly Bt2 million after Anant hired him to source scented hardwoods. He first threatened the victim then slashed his throat when he started to fight back.
Police found a loaded revolver and a switchblade on the suspect, who has been charged with premeditated murder, assault and possession of a firearm.
Wanchai's claim that he acted alone is being investigated after police found an SMS on his mobile phone that read "Is it done?"
