KOTA BARU: The motive behind the bomb blast and gunfire which injured four Thai policemen in a Sungai Golok sub-province yesterday morning is believed to be revenge.
A Thai security spokesman said they believed the arrest of four suspects of a drug smuggling syndicate recently led to the attack.
The spokesman said Thai police had seized more than 600,000 pills in an operation in Sungai Golok town, in one of their biggest seizures made over the past few years.
"Investigation into the bombing incident found that it was more of a revenge or dispute between certain individuals and the police.
"The group was not happy with the arrest of the four and seizure of the pills," said the spokesman.
It was reported that four Thai policemen were injured in an attack in Pasemus district in Sungai Golok sub-province early yesterday morning.
The victims, all with the rank of sergeant, were warded at Sungai Golok Hospital.
Following the incident, Thai and Kelantan police have beefed up checks along the border.
Thai authorities have closed more than five illegal jetties in Pasemas district while Kelantan police have increased their operations at Kampung Tersang and its surrounding areas.
A survey at Kampung Tersang today showed that the village was quieter than usual.
