Four people were hospitalized in New Zealand after a man armed with an axe began attacking diners at random at three neighboring Chinese restaurants, according to police and witnesses.

Police said the man began the attack at about 9 p.m. Monday in the north Auckland suburb of Albany. They said they arrested a 24-year-old suspect at the scene and had charged him with wounding and intending to cause grievous bodily harm. Police did not immediately offer a motive for the attack.

Auckland City Hospital said Tuesday one patient from the attack remained there in a stable condition. North Shore Hospital said it had one patient with moderate injuries and a second with minor injuries, both of whom were in a stable condition, and had earlier discharged a third patient.

A diner told the New Zealand Herald newspaper he was eating dinner with a friend when the man walked in and started attacking his friend, who was seriously injured.
