Police in Delhi have initiated a formal investigation following the discovery of unauthorized posters inside a Delhi Metro train carriage. The posters reportedly featured a QR code designed to direct individuals to an online group. Upon discovery, the materials were seized by law enforcement officials to prevent further distribution and to identify the source of the campaign.

The investigation has been escalated to include the Delhi Police Special Cell, a unit typically tasked with handling sensitive security matters. While authorities have confirmed that a case has been filed, they have not yet disclosed the specific nature of the online group or the identity of those responsible for placing the posters. The incident has raised questions regarding security protocols within the metro system, as the transit authority works to determine how the materials were posted without detection. As of now, no arrests have been announced, and officials are reviewing surveillance footage from the metro station and inside the train to track the individuals involved.
