Billboard are reporting that two members of Japanese pop group AKB48, along with a staff member, have been attacked by a saw-wielding man at a fan event in Takizawa city.

18-year-old Anna Iriyama and 19-year-old Rina Kawaei were apparently taken to hospital on the weekend following cuts to their hands and head, with the 24-year-old attacker being arrested shortly after the incident.

The 90-strong group (yeah, seriously) are big business in Japan, so we imagine the attacker will be severely punished for this.
