As police were inspecting the house in tambon Klong Udom Chonjorn yesterday morning, the homeowner’s younger brother presented them with a permit to manufacture and store fireworks.
The permit issued to the homeowner, Worawut Penjawattana, 36, expired on March 9.
The family’s relatives said the some 1,000 ping pong firecrackers that exploded might not have been the cause of the explosion.
They said police found that the blast occurred near a microwave in the kitchen where there were many battery-charging devices and three electric bicycle toys.
Police found some other 2,000 ready-made fireworks and ping pong firecrackers that didn’t explode in another room.
