A 6-year-old girl playing by her house in Yamagata. She was approached by two young men on bicycles who seem to resemble high school students. One of them used scissors to forcibly cut out the picture of 3 Pokemon on the little girl's shirt, leaving her with a 10cm hole over her chest. The girl was unharmed.
The girl told her father who reported to the police afterward. It is believed to be a prank and it is under investigation.
