From grainy pics to forensics: Inside Delhi police unit that finds missing people

NEW DELHI: Head constables Amit and Upender sit before a flickering computer monitor at the nodal headquarters of the Anti-Human Trafficking Unit (AHTU) in Rohini, their eyes scanning a grainy photograph of a teenager who vanished from a bus terminal in Delhi three years ago. For them, this isn't just another file in a mountain of paperwork; it is a puzzle that spans the breadth of the country.Over their two-year-long tenure at the unit, they have developed a sixth sense for the digital breadcrumbs left behind by the missing. They move seamlessly between the ZIPNet portal and the Vatsalya database, cross-referencing blurred CCTV stills with records from child care institutions (CCIs) in West Bengal and Odisha.Both are part of the AHTU under Delhi Police crime branch, a force that has turned the desperate search for the lost into a data-driven science of reunion. The genesis of this specialised unit dates back to 2014, following a directive from the Union home ministry to create a bulwark against human exploitation. What began as a focused response to human trafficking has evolved into a sophisticated 18-unit network that blankets the NCT of Delhi.From the bustling corridors of Indira Gandhi International airport to the sprawling railway terminuses, the AHTU operates with a mandate that covers the darkest corners of urban life: kidnapping, abduction, child labour, sexual abuse, and the rescue of those forced into begging. Stationed at Sector 16, Rohini, the AHTU acts as the central nervous system for these operations, coordinating with district units and non-governmental organisations to ensure no child falls through the cracks of a fragmented bureaucracy.For police commissioner Satish Golcha and special CP (crime) Devesh Srivastava Police, the AHTU is a high-priority unit that functions with a lean but elite force of inspectors, sub-inspectors and subordinate staff who treat every missing person report not as a statistic, but as a ticking clock.The AHTU's methodology is a blend of rigorous legal enforcement and empathetic social intervention. When a minor goes missing in Delhi, the machinery of the AHTU begins to grind within minutes. The law dictates the immediate registration of an FIR, but the unit's internal protocols go further.Within 24 hours, the details of the missing child are broadcast across ZIPNet and the Vatsalya portal, making the information instantly accessible to every police station in the city. This digital net is cast wide, involving the State Crime Records Bureau, the National Crime Records Bureau and the CBI, when necessary.The most effective work often happens on the ground though. Officers like assistant sub-inspector Gopal Krishan, who has spent seven years in the unit, know that the digital trail is only half the battle. Krishan has personally traced more than 750 missing or kidnapped persons, often travelling to remote villages in Bihar or Rajasthan to follow a lead. His work has earned him six Asadharan Karya Puraskar (AKP) awards. His colleagues like head constables Sukanya and Seema Tyagi are also celebrated cops in this domain.The legal framework under which these officers operate has recently transitioned to the provisions of Bharatiya Nyaya Sanhita, specifically sections addressing kidnapping and trafficking, alongside Juvenile Justice Act and Pocso Act. This legal arsenal allows the AHTU to not only find the missing, but also to dismantle the syndicates that profit from their absence.The unit's investigations are often monitored by high-level bodies like National Human Rights Commission and Delhi Commission for Women, ensuring that a victim-centric approach remains the priority."This is particularly crucial in habeas corpus petitions assigned by Delhi High Court, where the AHTU is tasked by the judiciary to produce a missing individual who may have been held against their will for years," explained an officer. The success rate in such cases is a point of pride for the unit and reflects inter-agency coordination.One of the most effective strategies in the AHTU's toolkit is the implementation of focused campaigns like Operation Muskan and Operation Milap. These month-long drives are designed to saturate the search effort, focusing specifically on children lodged in CCIs who may have been unable to communicate their origins. During these operations, officers become detectives of identity, using old photographs, half-remembered names of villages, or even distinct scars to link "unclaimed" children with "missing" reports.The vulnerability of children aged under 14 is given special emphasis, as they are the most at risk of being absorbed into labour or trafficking rings. The effectiveness of these drives was vividly demonstrated in Dec 2025, when a special drive ordered by special CP (crime) Devesh Srivastava led to the tracing of a staggering 795 missing persons and children in a single month."The AHTU's work also extends to prevention, with awareness campaigns in slums and schools, sensitising RWAs to the safety measures that can prevent a child from being snatched in the first place. Between 2020 and July 2025, the unit successfully traced over 1,100 minor children," said a DCP-rank officer.A significant portion of these were adolescent girls, a demographic that faces a unique set of perils. The tracing of these persons often requires the AHTU to navigate complex social realities, including the monitoring of placement agencies that provide domestic helps, which can sometimes serve as fronts for exploitation.To maintain the highest standards of operation, in early 2025, the AHTU sought and achieved IS/ISO 9001:2015 certification from the Bureau of Indian Standards. "This certification is more than a badge of honour; it is a validation of the unit's transparency and quality-driven framework, making it a rare example of a police unit that operates with the administrative precision of a high-end corporation," said special CP Srivastava.Ultimately, the story of the AHTU is not found in the ISO certificates or the technical portals, but in the moments of reunion that happen in the quiet corners of the Rohini office. It is found in the look on a mother's face when she sees a child she thought was lost forever, and in the satisfaction of an officer like Sukanya or Gopal Krishan as they close a file that has been open for years, ensuring that in the vast, chaotic landscape of the national capital, no one stays missing forever.
