Delhi Metro FIR: Police probe unauthorised posters on Airport Express Line
Investigators launch cyber and transit security inquiries after unauthorised notices questioning government performance were pasted inside train coaches.
Delhi Police have registered an FIR after unauthorised posters questioning government performance were found pasted inside a Delhi Metro train running on the Airport Express Line.
The posters, which carried slogans such as "Dissatisfied? You're not alone", included a suspicious QR code directing commuters to an external link. Transit authorities detected the material inside passenger coaches on the high-speed corridor connecting central New Delhi to Indira Gandhi International Airport, prompting security staff to alert law enforcement.
Officers removed the notices and initiated a formal investigation covering defacement of public infrastructure and security violations on the transport network.
What the police investigation covers
Investigators are examining security camera footage from metro coaches and station platforms along the Airport Express route to identify individuals who pasted the material. The corridor, known for high passenger volume and direct connectivity for international travellers and daily commuters, maintains round-the-clock surveillance overseen by transit authorities and security personnel.
Specialist cyber units within Delhi Police have also taken up the investigation to trace the origin of the QR code printed on the posters. Inquiries are focused on where the embedded link redirects, who registered the underlying domain or digital service, and whether the material represents an organised attempt to spread unsolicited messaging across key urban transport nodes.
Security protocols on the transport corridor
Delhi Metro trains undergo routine sweeping and monitoring at terminuses and maintenance depots. The Airport Express Line represents one of the premier segments of the capital's public transit infrastructure, constructed to deliver seamless, international-grade connectivity for domestic and foreign travellers.
Authorities have not disclosed the specific penal provisions cited in the police complaint, but matters involving unauthorised displays inside trains typically invoke relevant sections of the Delhi Metro Railway (Operation and Maintenance) Act alongside provisions related to public defacement.
Police said inquiries remain underway to identify the suspects involved in accessing the train cars to place the material.
