At about 8 p.m. on May 15, an explosion was heard in front of the National Theatre near Royal Field in Bangkok, Thailand, at a billboard instructing the public to attend the funeral of King Rama IX Bhumibol, next to a large tree, and the fragments of the explosion injured two nearby women, with symptoms such as tinnitus and injuries to their arms and feet, and they were taken to the hospital for treatment.
Due to the recent serious explosion of big C supermarket in Beakunen Province, southern Thailand, which caused a large number of people to be injured and property damage, and it was the opening season in Thailand, the explosion site was relatively sensitive, so there was public opinion that illegal elements created explosions to disrupt social order.
However, after the police and the bomb disposal team entered the scene to investigate, it was confirmed that the explosion was not caused by the bomb and no traces of gunpowder were found. Now only plastic fragments have been found, and it is speculated that the explosion is due to the aging of pvc plastic pipes on large billboard shelves, being blown by strong winds, excessive weight and air squeezing, etc.
