According to Focus Taiwan, a post by an unidentified observer on Threads reported that a power bank caught fire on a Bannan Line train at around 8 a.m., resulting in flames that were described as "huge." The post added that many passengers were made to disembark from the train.

Upon receiving the report, the metro traffic control center notified police, the fire department, and the rapid transit police brigade. A station master boarded the train to assess the situation and found that a passenger had already used a fire extinguisher on the device. The company th en arranged for about 1,200 passengers on the train to transfer to another train that arrived two minutes later, according to the TRTC. Police and firefighters will conduct an investigation into the incident, the company stated.
