Delhi Police Records Sharp 32% Rise in Forensic Deployment as New Criminal Laws Take Hold
Delhi Police has disclosed that its forensic teams examined approximately 24,500 crime scenes between January and May 2026 — a roughly 32% jump over the same five-month window last year — as the mandatory forensic-examination requirement under India's new criminal laws continues to reshape how the capital's police force investigates serious crime.
The Numbers Behind the Surge
According to figures shared by the Delhi Police, forensic teams attended close to 24,500 crime scenes in the first five months of 2026 — averaging roughly 160 scene visits a day across the capital. That represents an increase of about 32% compared to the corresponding period in 2025, a rise officials have directly linked to the statutory forensic-examination requirement introduced under the new criminal law framework rather than to any comparable rise in the underlying crime rate.
That distinction matters. Delhi's own crime data for 2025 actually pointed the other way, with police reporting murder cases dropping to 491 in 2025 from 506 in 2023, alongside a detection rate of 95.32%, and similar declines recorded across robbery, rape, and street-crime categories. The forensic workload curve and the crime-rate curve are, in other words, moving in different directions — which is precisely what a procedural mandate, rather than an actual crime wave, would produce.
Why Forensic Deployment Is Rising: The BNSS Mandate
The driver of this surge is Section 176(3) of the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023 — the code of criminal procedure that replaced the colonial-era CrPC when the new criminal laws came into force on July 1, 2024. The provision makes forensic examination of the crime scene legally mandatory, along with videography of the scene, for any offence punishable with seven years' imprisonment or more. The law also mandates audio-video recording of search and seizure in every criminal case, with recordings required to be submitted before the court electronically without delay.
This is not a discretionary best practice anymore — it is a procedural precondition for a valid investigation in serious offences. For a force the size of Delhi Police, that single clause has converted forensic teams from a specialist support function into a near-mandatory first responder alongside the local investigating officer, for a very wide band of criminal cases.
The Mobile Forensic Van Fleet — and the Parliament Complex Van
To absorb this load, Delhi Police currently operates 30 Mobile Forensic Vans (MFVs) across the city, with officials confirming plans to induct another dedicated van specifically assigned to cover the Parliament complex — a high-security zone that warrants its own standing forensic response capability rather than relying on district-wise rotation.
The MFV programme itself has grown considerably since its early rollout. Delhi Police's first batch of high-tech mobile forensic vans — procured through the National Forensic Sciences University (NFSU), Gandhinagar, and designed to standardise forensic procedures with one protocol across sexual assault, murder, dacoity, explosives, and narcotics cases — was formally launched by Union Home Minister Amit Shah in February 2023. Each van was fitted with 14 specialised kits covering fingerprint development, blood and semen detection, gunpowder and explosives detection, narcotics testing, and arson investigation, alongside equipment such as refrigeration units for biological evidence, stereo microscopes, and on-scene digital documentation tools.
Within just over six months of that induction, the vans had already made a significant dent in caseload: official figures showed the fleet had visited over 25,000 spots since February, with the largest single share going to house theft (10,492 visits) and burglary (4,164 visits), alongside 924 visits for rape and child sexual abuse cases, 700 for robbery, 352 for murder, and 474 for attempted murder. A senior police official at the time noted that the vans had enhanced evidence-collection capabilities and that forensic evidence plays an important role in securing convictions. The expansion to 30 vans by 2026 — doubling the original fleet — reflects both that early success and the scale of demand created by the BNSS mandate.
The Bigger Picture: A National Infrastructure Push
Delhi's numbers sit inside a much larger national recalibration of forensic capacity. In April 2026, the Ministry of Home Affairs issued a strict directive to all State Governments and Union Territories, setting a firm three-month deadline to strengthen forensic infrastructure, eliminate examination backlogs, and ensure timely forensic reporting nationwide, explicitly framed as an enforcement mechanism for the BNSS Section 176(3) mandate. The directive followed judicial concern over capacity: the Calcutta High Court had observed that the mandate would put immense pressure on existing central and state forensic laboratories tasked with analysing samples collected from crime scenes.
On the funding side, the Union Budget for 2026–27 allocated over ₹1,471 crore for forensic science nationally — the highest-ever dedicated forensic allocation — including ₹550 crore for the Interoperable Criminal Justice System, ₹145 crore for NFSU, and ₹130 crore for the National Forensic Infrastructure Enhancement Scheme. That scheme alone carries a ₹2,254.43 crore outlay through FY 2028–29 and funds nine new NFSU campuses and seven new Central Forensic Science Laboratories. Capacity on the ground has moved in step, if not fully in pace: the number of forensic laboratories nationally increased from 129 in 2023 to 154 in 2025, with more than 700 mobile forensic units deployed across states.
| Indicator | 2023 | 2025–26 |
|---|---|---|
| National forensic laboratories | 129 | 154 |
| Mobile forensic units (national) | — | 700+ |
| Delhi Police MFV fleet | 15 | 30 (+1 planned) |
| Union forensic science budget | — | ₹1,471 crore |
Analysis: What the Surge Signals
Read alongside falling crime figures, the 32% rise in Delhi's forensic scene visits is best understood as a story about procedural transformation, not rising criminality. Every serious offence that once might have proceeded on witness testimony and conventional investigation now routes, by law, through a forensic team at the scene. That has three practical consequences worth watching:
- Evidentiary quality is rising — On-scene forensic presence reduces contamination and improves chain-of-custody documentation, which should, over time, strengthen conviction rates in serious offences.
- Laboratory backlogs are the real bottleneck — Front-end collection capacity (vans, on-scene teams) has scaled faster than back-end laboratory analysis capacity, which is why the MHA's April 2026 directive focused heavily on eliminating examination backlogs, not just expanding fleets.
- Specialised infrastructure is becoming targeted, not just larger — The addition of a dedicated van for the Parliament complex, rather than simply adding vans to district pools, signals a shift toward risk-weighted forensic infrastructure planning for high-security zones.
For now, Delhi Police's disclosure offers a rare, concrete data point in a national conversation that has largely been discussed in terms of law and policy rather than operational load. A five-month total of 24,500 scene visits — nearly 5,000 a month — gives a measurable sense of just how deeply the new criminal law framework has embedded forensic science into the everyday machinery of policing in the capital.
