On 2 August 2019, two bombs exploded in the vicinity of the station, one in a bush beneath Chong Nonsi BTS Station and another at the entrance of the King Power Mahanakhon Tower. The event resulted in two minor injuries and the shattering of a platform screen door on the northbound platform. Exits 3–4 in front of Mahanakhon Tower were closed, including the lift, during the investigation. The local police found the suspect object and destroyed it with a high-pressure water gun.
