A motorcyclist ordered an elderly taxi driver out of the vehicle before stabbing him to death at a traffic light junction in Jalan Pasir Mas-Salor here this afternoon.

Sudin Awang, 67, from Pasir Puteh, was believed to have been attacked with a sharp weapon.

He died on the spot in the incident about 2.30pm. A female passenger seated in the rear of the taxi fled from the vehicle.

Kelantan Criminal Investigation Department chief ACP Ahmad Taufek Abdullah said the killer had earlier smashed the rear, front and driver's windows of the taxi with a hard object when Sudin stopped for the red light at the junction.

"At that juncture, the motorcyclist demanded that the taxi driver alight from the vehicle.

"When Sudin did as ordered, the motorcyclist stabbed him with a sharp object, causing him to collapse on the road," he told reporters at the scene of the crime.

Ahmad Taufek said the killer rode off in the direction of Salor and a female passenger who was seated in the rear of the taxi fled from the scene.

He said Sudin was from Kampung Wakaf Lanas, Pasir Puteh.

He appealed to witnesses of the attack to contact the police to facilitate investigations.

The body was sent to the Raja Perempuan Zainab II Hospital here.
