According to several accounts, the gunmen on a black pickup truck drove up the the victims' vehicle and commence fire, forcing the vehicle to stray off the road into the ditch.
Roads spikes were placed on the road to slowdown reinforcement.
While authorities tend to blame a new generation of Malay Muslim insurgents for most of the violence incidents in the region, a senior police officer and a security officer at the scene said not to rule out personal dispute as the cause of the attack.
They pointed to the fact that the officer, Pol Lieutenant Yart Raksiri, 52, suffered only minor injuries while the wife, Nipha Cheang-jiang, who was sitting on the passenger side, and their 17-year-old son son, whose name was not revealed, were riddled with bullets.
Nipha was a former member of the local Tambon Administrative Organisation (TAO).
About 25 rounds of M16 assault rifles and 9MM handgun were found at the scene. One officer said the gunmen pulled up next the victim's truck and commence fire at the wife. Pol Lt Yart suffered minor head injuries and was taken to Yala hospital for treatment. It was not clear if the bullet had nipped his head or because of the crash.
“Normally, after such an ambush, insurgents would come up and fire at least one shot to the head and take whatever belongings, such as weapons, with them,” said the officer who spoke on condition of anonymity.
It was not clear if the gun had taken Pol Lt Yart's M4 automatic rifle with them.
In separate incidents, suspected insurgents tossed a small bomb at police quarters and their nearby highway patrol office in Bacho district in Pattani at at about 7:30AM Thursday morning.
Authorities believe the same outfit fired several shots at an army outpost in the same district. No one was hurt in these attacks.
