SINGAPORE - Students of River Valley High School (RVHS) were rushed into classrooms for their own protection on Monday (July 19) after a 13-year-old Secondary 1 student was allegedly killed by a 16-year-old from the same school.

Several messages went out on social media as staff and students tried to make sense of what was happening. Some students also called their parents, sobbing on the other end of the phone.

The Straits Times looks at how the day unfolded:

11.40am: Police receive a call for assistance at RVHS, which is located at 6 Boon Lay Avenue. Officers arrive quickly at the scene and find a 13-year-old student with multiple wounds in a school toilet.

The boy is later pronounced dead by a paramedic.

He tells her to run to a nearby mall, but she is stopped from leaving the school grounds. She later tells him she is safe with the teachers.
