Tokyo : A Japanese man who allegedly kicked a fellow diner to death in a fight over seats in a noodle bar calmly returned to his food as the other man lay dying. Shinichiro Imanishi, 37, was being questioned in connection with the death of a 49-year-old man whom he allegedly threw to the floor and then stamped on repeatedly, a police spokesman told AFP. The trouble erupted when Hisao Kitajima pulled a chair which Imanishi was using to rest his foot on, the spokesman said, adding Kitajima died of his injuries two days later. Imanishi, who weighs 120 kilogrammes, did nothing to help his victim after the frenzied attack in Tokyo, instead ordering a bowl of noodles, local media said.
