A high school student attempted to kill a female junior high school student with a blunt object on her way to school... Presumed to be a stalker (South Korea)

A male high school student was arrested by police for attempting to kill a female middle school student with a blunt object on the first day of school. On the 19th, the Sannok Police Station in Ansan, Gyeonggi Province, filed a murder lawsuit against the student.
A high school student, Mr. A, was arrested on the spot on suspicion of attempted murder and is currently under investigation. Mr. A hit Ms. B on the head with a blunt object while she was on her way to school near a junior high school in Changnok-gu, Ansan-si at 8:16 a.m. today, and then swung the weapon at her.
The suspect is accused of injuring the victim by spinning the handle around. A was subdued by passersby and then arrested by police officers. B was taken to the hospital in a state of heavy bleeding.
The police presume that A was stalking B, which led to the crime. It was reported that there was no history of reporting between the two.
However, last month, A-kun was persuaded by a school police officer who had received a report from the school to leave both schools.
It was understood that the student had a history of being hospitalized with the consent of his parents. Details of the report from the school were not provided.
A police source said, "Mr. A was following Mr. B around on the first day of school.
"It is believed that he committed the crime in the following manner." Meanwhile, the police plan to apply for an arrest warrant for Mr. A as soon as they finish their investigation.
