The fivekilo explosive was planted under the roof of an unused building in Pracha Bamrung school in RaNgae district, and was detonated through mobile phone signals when a sixman patrol went in to take a rest. The blast seriously wounded patrol leader Sergeant Abhisit Srianurak.
Quoting witnesses, security officials said a black Isuzu pickup was seen speeding from the school not long before the patrol finished its morning escort mission for teachers and students and was about to enter the building which was its rest area. Police later theorised the explosion was the work of insurgents.
