TOKYO: A Japanese gunman accused of shooting dead a construction worker and wounding three others died on Wednesday after he also shot himself following a long and tense standoff with police, news reports said. Yasuhide Mizobata fled into an apartment building on Tuesday afternoon after firing repeatedly at officers who challenged him, a force spokesman said. About 17 hours later the suspect shot himself in the abdomen, public broadcaster NHK and Jiji Press reported. NHK footage showed police storming the building after hearing a gunshot as an ambulance apparently carrying the suspect sped off. The broadcaster said police arrested him. He was then treated in hospital but later confirmed dead, NHK said.
