TOKYO (Kyodo) -- A man under arrest for stabbing a woman repeatedly has told police that the attack in western Tokyo was sparked when the victim rejected a gift from him, investigative sources said Sunday.
Tomohiro Iwazaki, a 27-year-old man, stabbed Mayu Tomita, a 20-year-old college student, more than 20 times including in the neck, chest, arms and back, shortly after 5 p.m. Saturday in Koganei. The assault came shortly before Tomita was due to take the stage to perform with other women in an idol event.
Iwazaki, who was arrested at the site, told police, "I sent a gift (to Tomita) but it was returned. I asked her why but she gave an evasive answer, so I became mad and stabbed her numerous times."
Iwazaki also told the police that he intended to kill her and carried a knife for that purpose, indicating it was a premeditated assault.
Tomita has been appearing in pop idol shows and television programs for children, and the police suspect Iwazaki is a fan of hers.
According to the police, the suspect intercepted Tomita in hopes of talking to her at JR Musashi-Koganei Station before the assault occurred.
Security camera footage shows a man appearing to be Iwazaki following Tomita from the station to the site of the crime.
Tomita, who remains in hospital in a critical condition, had earlier visited a police station near her home in Musashino seeking advice after Iwazaki had harassed her online via social networking sites such as twitter. She mentioned Iwazaki by name when speaking to police.
Learning from Tomita on Thursday that she planned to appear at an idol event on Saturday, officers at the Musashino police station asked the police in Koganei to respond if they receive an emergency call on the matter.
The police will now scrutinize the perpetrator's messages to confirm his link with the attack while also assessing whether the police handled the incident appropriately.
