TOKYO – Two teenage members of Japanese girl group AKB48 were in hospital Monday after being attacked by a man wielding a saw at one of the band’s regular meet-the-fans events, managers said.

Rina Kawaei, 19, and Anna Iriyama, 18, both suffered broken bones in their right hands and received cuts on their arms and heads from the 50-centimeter (20-inch) saw at the event in Iwate in northern Japan.

Reports said the attack came after a mini-concert early Sunday afternoon as fans were lining up to shake hands with performers inside booths.

Kawaei and Iriyama were inside the same booth when a man in the queue suddenly produced a saw, the Yomiuri daily said.

Fans told Japanese media they heard a shriek, apparently from one of the young women, saying “Stop it!”

Some of the 100 or so staff and security guards at the event pounced on the attacker and held him until police arrived, reports said. A member of staff was also hurt in the melee.

One fan described how Kawaei was covered in blood when she was taken away by medics to a waiting ambulance.

Both girls were expected to be discharged from hospital on Tuesday, a statement from the band’s management said.

A 24-year-old man, identified as unemployed Satoru Umeta, has been arrested on suspicion of attempted murder, police said.

“We have started questioning the suspect this morning to know details, including his motive,” a detective with Iwate prefectural police told AFP.

AKB48 is part talent show, part pop act, a venture in which a pool of more than 100 girls and young women compete for a spot in the limelight with each new catchy, but formulaic, hit.

The group — one of the most successful acts of all time in monetary terms — is built on their accessibility to their legion of fans. They appear at regular events all over the country to shake hands and pose for pictures, as well as on social networking sites.

Fans are given around seven seconds to pose with their idols, the Yomiuri reported Monday, before they are moved off by security heavies eager to prevent problems and maintain the through-flow.

Members must strive constantly for popularity if they wish to retain their spot, and girls who contravene strict rules — such as having boyfriends — are punished by being dropped back into the general talent pool.

Line-up changes often sound the death-knell for musical acts. But the frequent rotation of AKB’s members is key to keeping them at the top of their game in Japan’s fickle pop scene.
