The bomb in a 20-kilogram cooking cylinder placed in a green plastic bag was discovered at 9am on Sungai Padi-Chatwarin Fall Road in Tambon Paluru.
The Border Patrol Police Company 447 Explosive Ordnance Disposal team defused the bomb by shooting water from a high-pressure hose at a its radio-triggered detonator, while a device scrambled radio signals. They later disassembled the bomb near the scene and submitted the components to forensic officers and police investigators.
Pongsathorn Sonjit, who led the six-member patrol, said the team had been travelling on three motorcycles returning from protecting teachers when they spotted the bag under the power pole and alerted authorities.
