Sporting a black right eye, Chim told police that a man she knows only as Apichart came into the bar, boasting that he was under the protection of a senior police officers.
Firefighters arrive at Thepprasit Soi 17 to find the no-name club fully engulfed.
He flirted with the owner, who turned away his advances. In retaliation, he smashed her in the face with a motorcycle helmet and hit her elsewhere several times.
Chim said she quickly shut the shop and ran off, but Apichart was angry and burned down her business, she claimed.
Fortunately, Chim was able to snap a photo of Apichart during one of his karaoke-bar boast sessions. Armed with it, police hope to find the arsonist.
