In 1986 a wave of highly publicised armed robberies in Bendel State (now Edo and Delta states) challenged public order in southern Nigeria and provoked an urgent response from federal security authorities. The figure most widely identified with that campaign was Lawrence Nomanyagbon Anini; his principal lieutenants, including Monday Osunbor, were later arrested, tried and executed. The episode matters because it exposed corruption and weaknesses within policing structures, shaped subsequent investigative practice and became a lasting reference point in debates about crime, police reform and state legitimacy in Nigeria.
The rise of Anini’s gang
By mid-1986 Anini and his associates carried out a string of violent robberies, ambushed cash-in-transit vehicles, and at times attacked police patrols. Press reports and later official accounts described the gang as audacious and mobile; their success depended in part on exploitation of poor internal controls and, according to investigations and later testimony, occasional collusion or leakage of information from within the security apparatus. The resulting public alarm and political embarrassment for the military government created intense pressure on police leadership to arrest the gang quickly (Osayande; Falola & Heaton).
Institutional weaknesses revealed
Two structural problems framed the crisis. First, policing capacities at state level were uneven; some local commands lacked modern investigative capabilities and suffered from low morale and corruption. Second, information flows between police commands, and between police and military authorities, were imperfect. These factors made an intelligence-led response both necessary and politically urgent. The Anini affair therefore became a test of whether Nigeria’s security services could co-ordinate, protect sources, and restore public confidence without resorting to extrajudicial measures (Falola & Heaton).

The manhunt and arrest
Authorities restructured their approach: they consolidated intelligence, restricted operational knowledge to a small number of trusted officers and cultivated informants. Deputy Inspector-General and senior commissioners directed resources to Bendel State; tactical teams worked on leads developed from surveillance and tip-offs. According to official accounts and memoirs by senior officers involved in policing at the time, the breakthrough occurred in early December 1986 after a concerted, intelligence-guided operation. Anini was arrested and reported wounded; several associates, including Monday Osunbor, were apprehended in the same period (Osayande).
Trial, conviction and execution
Following arrest, Anini and key associates faced trial under the criminal justice procedures of the time. Court records and contemporary reportage indicate prosecutions were pursued for armed robbery, murder and related offences; the legal process culminated in capital sentences. Anini and principal lieutenants, including Monday Osunbor, were executed in 1987. The convictions and executions were presented publicly by the government as the restoration of order, though commentators also noted the episode’s wider role in prompting police reform (Falola & Heaton).
Aftermath and significance
The Anini case had several consequences. It prompted internal disciplinary reviews and removal of officers suspected of collusion; it encouraged the adoption of more structured intelligence procedures in high-profile investigations; and it generated public debate about policing standards and civil liberties. For scholars of Nigerian policing and crime, the episode illustrates how organised criminal violence can flourish where state institutions are weak and how political pressure can shape investigative methods (Osayande; Igbinovia).
The case also entered popular memory in ways that mixed fact and myth. Over time, dramatic retellings emphasised supernatural rumours, singular heroic captures and lurid details. Careful historical, cross-checking court files, police memoirs and contemporary news reporting, helps separate verifiable actions from folkloric embellishment.

Author’s note
This account reconstructs the Anini affair from contemporary reporting and later police memoirs. In late 1986 the Anini gang’s campaign of armed robbery exposed institutional weaknesses within local policing and sparked a concentrated, intelligence-led response that resulted in the arrests and prosecutions of Lawrence Anini and his principal lieutenants, including Monday Osunbor. The wider lesson is institutional: law enforcement succeeds best when it combines professional investigative standards, protection of informants and transparent procedures; conversely, corruption and poor inter-agency coordination create openings for organised violence. The episode therefore remains instructive for debates about police reform, accountability and the rule of law in Nigeria.
