A Chennai BSNL office fire, likely from an electrical fault, disrupted services but caused no injuries.

A fire broke out at a BSNL office on Anna Salai in Chennai on December 20, 2025, around 9:30 a.m., likely due to an electrical short circuit or battery explosion on the second floor. Thick smoke spread to multiple floors, prompting emergency response and traffic disruptions on the busy road. No injuries were reported as the office was closed on a holiday. Firefighters from several stations worked over an hour to contain the blaze, which damaged servers and disrupted online payment systems for TANGEDCO and backup services for the 108 ambulance system, though the main 108 control room remained operational. The exact cause is under investigation.
