A policeman has been arrested for trespassing in a store in Yokosuka, Kanagawa prefecture, police said Sunday.

According to police, the 26-year-old officer, Hayato Sakai, entered the organic food store by the staff entrance at around 4:30 p.m. on Saturday. TV Asahi reported that at the time there were no customers, and an employee contacted police to report a suspicious intruder.

Police said Sakai was drunk when they arrived. He was quoted by police as saying he had been out drinking with a friend after going off duty.

A Kanagawa prefectural police spokesman apologized for the incident at a news conference and said Sakai's behavior was unacceptable for a police officer.
