On April 1st, the police revealed that they had investigated SNSD member A after receiving a report from a man who claimed she had hit his face while joking around.
According to the police, A, who is friends with B, were at a mutual friend's house on the 30th. While joking around, A had shoved B's hand away and hitting his eye with her finger in the process.
As they were on the second floor, A had jokingly said she would fall off to the first floor. B tried to hold A back but A hit his hand away, causing the accident to occur in that moment. Angered, B reported A's actions at a nearby police station. The two were investigated twice on the night of the accident and the following day.
B had told the police, "I was hit while joking around but now that I think about it, I don't think she purposely meant to hit me."
Police also revealed, "The man was not hurt. We had to investigate the issue because of the report but it seems the issue will mutually end as just an incident."
(tl;dr: An SNSD member A tried to joke about jumping off the second floor of a friend's house and her male friend B tried to hold her back. A shoved B's hand away, accidentally hitting his eye in the process. B got mad and reported it.)
