Owner Yu Yu Chou told local newspaper reporters : ' I admit to killing the dog , but the meat is for my own personal use , not for my customers . ' Police received a tip-off from a restaurant client who heard the sounds of a howling dog at the back of the establishment . After peeking over the back fence to investigate , the horrified client witnessed two cooks in the act of killing the defenceless animal . In total five arrests were made at Mr Yu Yu Chou 's restaurant , including three workers of Chinese nationality . An official was filmed pulling a beheaded dog from a storage barrel during the raid .

' The AFN news agency took video evidence of the police bust .
