Initial report said that the first bomb explosion occurred in front of 7-Eleven convenience store on Polpichai road in front of the Southern Engineering College at about 1.30 pm. About five people were slightly injured.
The second bomb occurred about half an hour later in front of the police apartment just opposite Hat Yai police station. Shortly afterward, a third bomb went off at the car park of the police station causing several parked cars to catch fire.
It was initially suspected that the bomb attacks were perpetrated by southern separatists who normally confined their insurgency activities in the three southern provinces of Yala, Pattani and Narathiwat and some districts of Songkhla.
