Japanese police nabbed a former gangster on Friday, ending a more than 24-hour standoff during which the man shot a policeman dead after wounding his own son, daughter and another police officer and holing up in his suburban house.

Television footage showed over a dozen policemen with helmets and shields surrounding the former gangster after he came out of his house holding a plastic bag and bottle. Media reports said he has been arrested on suspicion of attempted murder.

In the latest shoot-out to rattle Japan, the former gangster fatally shot a policeman who was a member of a special assault unit on Thursday evening while a colleague who had been hit earlier was being rescued.
