Police in Tokyo are hunting for a male suspect after receiving a report Sunday morning that a woman was stabbed in the capital¡¯s Minato Ward.

The incident occurred in the basement of a building in the busy Akasaka area, according to police. The victim, a singer in her 40s, sustained serious injuries to her side and her left hand, with a stab reaching her organ. She was conscious when taken to the hospital.

The suspect, who was described as wearing black work clothes, fled the scene on a bicycle, carrying a knife, and appeared to head to the direction of the Aoyama district.

Investigators say the woman, who was visiting a store in the building¡¯s basement, had no prior acquaintance with the suspect. The woman was expected to perform at a live music club in the building¡¯s basement, and was attacked while she was waiting for the club to be unlocked.

The club¡¯s manager said they didn¡¯t see any suspicious person when they went outside of the building to take out the garbage, but heard a scream after they went back to the club. Police believe there is a possibility of the suspect following the woman to the basement.

Investigative sources said Monday that security camera footage showed the suspect had been wandering around the area by bike or foot for at least an hour before the incident.

The club also found that a poster for the performance put up at the building¡¯s first floor was crossed out with a black spray ink. Police officials are investigating whether the case is related to the stabbing.

According to the club¡¯s website, an afternoon performance was scheduled from 1 p.m. to 3:30 p.m. Sunday, and an evening performance from 7 p.m. to 10 p.m., both of which were canceled.

The assault happened about 150 meters southwest of Tokyo Metro¡¯s Akasaka-Mitsuke Station in a busy area lined with restaurants and office buildings.
