Nigeria held 80,812 people in correctional facilities, including 51,955 awaiting trial, as overcrowding and prolonged detention left nearly two-thirds of inmates behind bars without convictions, Vanguard reported on October 17, 2026. Another 24,913 were convicted inmates, and 3,850 people were in other detention categories. The awaiting-trial population made up 64 per cent of all inmates.
Who Pays for Delay
People awaiting trial can spend months or years in detention before their cases are decided, including people eventually discharged or acquitted. Justice-sector stakeholders say delays stem from slow investigations, late legal advice, inadequate representation for indigent defendants, repeated adjournments and other bottlenecks.
National Bureau of Statistics data showed unsentenced inmates rising from 47,610 in 2017 to 53,790 in the second quarter of 2025. Total inmate numbers climbed from 69,946 to 81,710 over the same period. The figures reflect a growing population held before conviction.
On May 15, 2026, the ECOWAS Court of Justice found that prolonged detention of awaiting-trial inmates, and the resulting overcrowding, violated rights to liberty, dignity, fair hearing, presumption of innocence and trial within a reasonable time. The National Human Rights Commission has also identified prolonged pre-trial detention, arbitrary arrest, torture, denial of access to lawyers and poor detention conditions as persistent concerns.
The Federal Government's independent investigative panel is examining allegations of corruption, abuse of power and human rights violations in correctional institutions. It reviewed 86 custodial facilities across 23 states and the Federal Capital Territory, identifying infrastructure deficits and security risks in facilities including those in Delta, Edo, Sokoto and Kaduna states.
Budgets, Contracts and Conditions
Many correctional centres date back decades, and some are more than a century old, the House Committee on Reformatory Institutions warned. Dilapidated walls, poor ventilation, obsolete security systems, too few vehicles and weak perimeter protection complicate security and rehabilitation.
The investigative panel found evidence of inmate malnutrition and alleged abuses in feeding-contract administration. It recommended increasing the daily feeding allowance from N750 to N3,000. Vanguard's August investigation reported complaints from inmates and former inmates about food quantity and quality at some centres; correctional authorities denied systemic starvation and defended official arrangements.
In its 2025 budget performance, the Nigeria Correctional Service, or NCoS, reported spending ₦27.28 billion, or 71.7 percent of its overhead releases, on inmate feeding. It also reported ₦10.75 billion in outstanding food-ration obligations. For 2026, the Service proposed ₦14.83 billion to feed an estimated 91,100 inmates at ₦1,125 per inmate per day.
Capital funding fell well short of the Service's allocation. In 2025, the government released ₦3.22 billion, or 22.2 per cent of the NCoS's ₦14.50 billion capital allocation, leaving ₦11.27 billion unreleased. The Service sought substantially higher capital funding for 2026, identifying construction and rehabilitation, vehicles, security equipment, information technology, inmate biometrics and prison farms as areas needing investment.
Oversight and the Limits of Reform
The panel examined allegations involving corruption, abuse of power, torture, illegal inmate movements, drug trafficking, unauthorised visits and smuggling prohibited items. An April report based on panel proceedings detailed allegations that inmates operated businesses, including point-of-sale operations, and that officials helped facilitate prohibited activities.
In May, the NCoS said it destroyed 1,167 confiscated mobile phones and other prohibited items recovered during nationwide searches. It also reported recovering ₦2.569 million in smuggled cash and sanctioning 147 officers for contraband-related infractions. In August, after an inmate at Ibara Medium Custodial Centre in Abeokuta, Ogun State, livestreamed on TikTok using a prohibited phone, the Service removed the officer in charge and two other principal officers pending investigation and transferred the inmate.
A 2019 law changed the Nigerian Prisons Service into the Nigerian Correctional Service and gave it a mandate for reformation, rehabilitation and reintegration. The law requires educational and vocational programmes, psychological and counselling services, and opportunities for inmates to develop skills and generate income. A 2026 study of medium-security facilities in Kwara State found vocational training in the centres studied but said it was fully functional in only one. Digital learning infrastructure was absent or non-functional in all three facilities examined, and overcrowding constrained rehabilitation in two.
The NCoS expanded parole, probation and community service and reconstituted parole boards, but figures reported in July showed 1,271 Nigerians serving non-custodial sentences nationwide. The Service proposed ₦37.99 billion in 2026 to expand those measures across the 774 local government areas. It also proposed a total budget of ₦198.85 billion, including ₦138.30 billion for personnel and ₦50.40 billion for recurrent overhead, and requested an additional ₦90.38 billion to strengthen capital expenditure. Its stated outstanding liabilities included ₦30.38 billion in promotion arrears and ₦25.16 billion owed to contractors.
The investigative panel's findings put accountability, procurement, contract administration, oversight and discipline alongside infrastructure and inmate welfare. The report also identified faster investigation and prosecution, improved access to legal representation, greater use of non-custodial sanctions and more efficient court processes as ways to reduce the number of people entering custodial centres.
