Malaysian police have arrested a 16-year-old student after he live-streamed an attack on a teacher with an axe at a private school in Kuching, the capital of Sarawak state.
CCTV footage shows the teenager entering a classroom at around 7.50am on Wednesday, hitting the female teacher once with an axe before leaving.
He re-enters through a second door and swings the axe at a student as others flee the room. As the teacher tries to intervene, he attempts to hack at her again but is subdued by two male students and has the axe taken away.
