The incident occurred at around 8am after a police parade at the station, said Mueang Pattani police chief Jeffery Sulaiman.

“Initial investigations revealed that the bomb was believed to have been attached to a motorcycle parked near the police station,” he told reporters at the scene.

Jeffery said the 20-year-old Malaysian man from Kuala Lumpur sustained injuries from shattered glass caused by the explosion.

The man was in a car waiting for his wife, who was lodging a report on missing travel documents at the police station, when the explosion occurred, he said.

“The victim’s car was only about 10m from the explosion site, and the vehicle’s windows shattered due to the blast impact,” Jeffery added.

The victims were taken to Pattani Hospital for treatment.

“The police are actively investigating to track down the perpetrators,” Jeffery said.
