SINGAPORE – A student of River Valley High School (RVHS) was allegedly killed on campus on Monday (July 19) in an incident which saw staff ordering students to remain in their classrooms.

In a message to parents, the school said a “serious incident” had taken place at the school involving a Secondary one boy.

“The case is now under police investigations and the police are being assisted by a Sec 4 boy,” the school added.

The Straits Times spoke to a parent – Mr Huang, a 43-year-old who works in the IT industry – at about 3pm.

He had rushed to the school after receiving a message from his daughter in Year One that said there was someone allegedly wielding an axe in the school.

Mr Huang showed ST the text message he received from his daughter at 11.50am and a video of students running on school grounds. She texted him about five minutes later, saying the situation under control. But he said he drove from his home in Pasir Ris to the school anyway.

Education minister Chan Chun Sing released a statement at 4.25pm saying his ministry is  working closely with Singapore Police Force on the investigations.

“We are all shocked to receive news of the tragic incident at River Valley High School this morning,” he said, adding that the safety and well-being of students and staff are of paramount importance.

When ST arrived at the school at Boon Lay Avenue at about 1pm, a crime scene investigation van, an ambulance and at least four police vehicles were already there.

The back gate was closed off, but students who needed to leave the campus were allowed to do so past 2pm. The rest were gathered at the school hall and briefed by school staff.

At about 3pm, the rest of the students were allowed to leave the school compound. Several parents were already at the school waiting to pick up their children. A Health Sciences Authority (HSA) van arrived at the scene at about 3.30pm with a forensic science team.

A mother, who wanted to be known only as Madam Chin, said she had received a call from her daughter, who is in Sec 3, at about noon. The 40-year-old, who arrived at the school at 4pm, said her daughter was sobbing on the phone when she called.

The student was unclear about the threat but said she was moved to another classroom, to a safe place with teachers around her. She told her mother she will be released by the school at about 4pm.

RVHS has students aged between 12 and 18, as it offers the six-year Integrated Programme which allows students to skip the O levels and instead take the A levels in their sixth year.

Staff who spoke to The Straits Times said there was supposed to be a lunch break at 1pm, but the students were told to remain in their classrooms instead. No explanation was offered.
