It’s been reported that AKB48 member Kashiwagi Yuki’s stage costume was stolen from a warehouse, and put up on an online auction site.
According to the Metropolitan Police Department, Kashiwagi’s stage costume was put up for auction by a male high school student (17) from Shiga Prefecture. He commented, “I bought it from someone on the internet. I didn’t know it was a stolen item.”
Last November, a management employee found the stage costume on an auction site. They confirmed that it was the real thing after getting their hands on the item with a successful bid of 300,000 yen (around $3900 USD). They reported a damage report to the police, and they are investigating this as a property crime.
Regarding the issue, the management stated, “We will refrain from making comments.”source
Someone either in security or staff had to do it.
