Police have arrested three students who they believe to be responsible for the Soi Rama IX 57/1 bombing, ruled out as unrelated to the other bombings by Police Maj. Gen. Theerapong Wongratpitak.
Dunan Liangson, 19, a 17-year-old minor and a 15-year-old minor were arrested. Police also seized a homemade bomb, pen gun, and knives from them. The three have been charged with illegally owning and carrying a weapon.
Theerapong said the three, all students, are “unrelated to the bombings in the city,” and that the three had stashed weapons in the soi for self-defense.
While the other bombings struck urban areas and government centers, Soi Rama IX 57/1 is located in the western suburbs of the city. The blast injured three street cleaners.

A suspected arson raged through Miniso store inside Siam Square One shopping mall on Friday 4am, but the incident happened to unfold to the media only at night.
The flame blazed way before opening time at 4:45am, damaging products on the shelves before fire sprinklers were activated.
Police found wires and parts of what appeared to be an electric circuit among the wreckage, but did not confirm whether the fire is related to the attacks. However, a CCTV footage obtained by Khaosod shows a suspicious man putting a device inside one of the dolls before putting it back on Thursday afternoon.
