At a middle school in Seoul, South Korea, a female student stabbed a male student with a deadly weapon during a fight and was arrested red-handed. On the 8th, Seoul Songpa Police Station gave special injuries to Ms. A, a middle school girl.
An investigation has been launched into suspicion of harm. Mr. A is accused of stabbing Mr. B, a male student, with a deadly weapon during a fight in front of the main gate of a junior high school in Songpa District at around 6 pm on the same day. Mr. A and Mr. B go to the same school
He is currently attending school, but he is in a different class. It was known that there were other students in the area at the time, and the police were called to the scene immediately after the incident and arrested Mr. A.
Mr. B was immediately taken to the hospital for treatment, and it was determined that his injuries were not life-threatening.
With the consent of Mr. A's guardian, the police investigated Mr. A's possession of the murder weapon and whether he had any prior plans to commit the crime.
