Two Bangkok Bank branches in Chiang Mai came under separate bomb attacks yesterday, with slight property damage but no casualties reported.
Police theorised two attackers on a motorcycle, seen in security camera footage, planned to bomb the bank and selected the shop as their secondary target after noticing it had a surveillance system.
At the Chom Thong district branch, a bottle bomb was lobbed over a wall near the side of the building at around 3am, causing no property damage. The bomb consisted of gunpowder, petrol and fertiliser-based explosives, police said.
Security camera footage did not catch the attack. Police said both attacks could have been politically motivated.
