OK, one more time people. When a creepy obsessed fan sends you a gift just send him a simple thank you note and then ring the police ASAP. A Japanese pop singer is fighting for her life after she returned a watch sent to her from a psychotic fan and he turned up at her concert and went crackers. Mayu Tomita was stabbed over 20 times when she didn’t give him a straight answer as to why she returned his present. I’m guessing she was lost for words …. She is now lying unconscious in a Tokyo hospital.
