A 50-year-old man who had been drinking heavily in Tokyo's Kabukicho district died after a bar manager and three others robbed him and left him on the street, police said Sunday.

The bar manager, Mitsuko Ogawa, 73, and two female bar workers, aged 24 and 74, were arrested Saturday on suspicion of robbery and negligence resulting in death.

Also arrested was Yuta Izawa, 22, who works at a multipurpose rental space facility in Kabukicho, on charges of abandoning the man on the street.

The victim, Masaru Asada, a salaried worker from Nerima Ward, was taken to a hospital where he was confirmed dead about nine hours later, the police said.

The four under arrest have admitted to the charges.

According to investigators, Ogawa had the two workers accompany Asada to a nearby cash dispenser after he had become extremely drunk early Saturday. They were videotaped by a security camera at a nearby convenience store.

Ogawa then had Izawa and two other men carry Asada, who was practically unconscious, to a nearby street and leave him there. The two other men have yet to be unaccounted for.

Asada went to the bar by himself after drinking with colleagues elsewhere.
