The police patrol car was attacked while it was doing its rounds under a bridge.

Initial investigation on Monday showed that the bomb had been hidden in a small gas tank and triggered via radio communication.

The authorities believe the attack was in retaliation to a suspected insurgent being killed in a recent gunfight with police in Narathiwat.
