According to the police website, the incident involving 12 vehicles occurred on Feb 28, 1990 at Km31 of the Kuala Lumpur–Karak Highway in Pahang.

The FRU officers, from Troop 4B, were en route from the police training centre (Pulapol) in Kuala Lumpur to Kuala Terengganu for an operational readiness drill.

Investigators later found that an express bus descending a hill had lost control after its brakes failed. It struck two cars before colliding head-on with the FRU truck, which was leading a convoy of five vehicles.

“The force of the impact drove the FRU truck beneath the bus, which was then hit by a fuel tanker attempting to avoid the crash,” the report said.

Five officers died at the scene, while six others succumbed to their injuries at the Kuala Lumpur general hospital.

The victims were identified as Hilmi Ismail, Saaid Hassan, Shahimi Lazim, Som Puteh, Lazim Admin, Abd Razak Sharif, Wan Mazland Bidin, Razali Bidin, Samsudin Hamad, Sazali Hussin and Kok Kiong. Four civilians also lost their lives.

This morning, nine FRU personnel were killed and two others critically injured when their truck collided with a lorry transporting gravel stones on Jalan Chikus–Sungai Lampam in Teluk Intan.

Eight officers died at the scene, while a ninth died later at Teluk Intan Hospital. The cause of the crash is under investigation.
