Japanese pop star Mayu Tomita is in a coma in critical condition after being stabbed multiple times by an obsessed fan.

Following his arrest, The Japan Times reports Iwazaki confessed to the stabbing, telling police he “lost his temper.”

Earlier in the month Tomita had notified police about her attacker after he began posting threatening messages about her on social media.

Tomita, a 20-year-old J-pop star previously in the group Secret Girls, was scheduled to perform that night in the same building in Tokyo. As of Monday evening she remained unresponsive in hospital from the stabbings to her neck and chest.
