The mayor of the Japanese city of Nagasaki, a prominent anti-nuclear activist, was shot by a yakuza gangster on Tuesday and is in critical condition, officials said. Mayor Iccho Ito was shot twice late Tuesday outside the city's main train station by a gangster reportedly disgruntled over damage to his car at a public works site, according to Nagasaki prefectural (state) police official Rumi Tsujimoto, according to AP. Footage from the southwestern city of Nagasaki showed several officers wrestling a man to the ground and pushing him into a police car, and an ambulance leaving the scene as police shouted for bystanders to make way. Tetsuya Shiroo, a senior member of Yamaguchi-gumi, Japan's largest organized crime group, was arrested on the spot for attempted murder, police said. Shiroo has admitted to shooting Ito with a handgun with the intent to kill, Nagasaki chief investigator Kazuki Umebayashi said in a televised news conference. -- SPA
