Two women sustained minor injuries after a man slashed them with a kitchen knife in Sapporo’s Atsubetsu Ward on Friday evening, police said.

According to police, 30-year-old Atsushi Nishino attacked two women at random on the street, then burst into a dry cleaning shop and grabbed a 66-year-old clerk from behind in a head lock.

Police were alerted and arrested Nishino on charges of assault. He was quoted by police as saying that he didn’t know any of the people he attacked but gave no motive.
