Nigeria’s security agencies have intensified investigations into an alleged coup plot aimed at destabilising President Bola Ahmed Tinubu’s administration. The probe reportedly involves both military officers and politicians from the southern and northern regions of the country.
According to top security sources, the Defence Intelligence Agency (DIA), working with other security units, has been interrogating several officers and politicians suspected of involvement in the plot. The investigation, which began several weeks ago, followed intelligence reports indicating a possible attempt by some individuals to incite unrest and weaken confidence in the government.
It was gathered that about 16 military officers have already been detained for questioning over what authorities described as “unprofessional conduct.” Sources said the arrests are linked to a wider security operation designed to uncover networks allegedly working to destabilise the country.
Some of the politicians under investigation are said to be influential figures from both the northern and southern parts of Nigeria, including a well-known southern political leader accused of providing financial support for the plot. A few suspects are also believed to have links with traditional institutions and political power blocs.
While the Defence Headquarters has not released the names of those in custody, it confirmed that investigations are ongoing. A senior defence official, who spoke on condition of anonymity, said the agency is “not leaving anything to chance,” stressing that both civilian and military actors found culpable will face prosecution.
“The integrity of our democracy and the stability of the Nigerian state are non-negotiable,” the official said. “We have intelligence linking certain individuals—both politicians and officers—to plans that could threaten national security. The law will take its full course once investigations are concluded.”
The alleged coup plot has stirred concern among citizens, especially following similar military takeovers in some African countries in recent years. However, analysts have urged caution, warning against speculation until the authorities release official details or evidence of the alleged plot.
As of the time of filing this report, no formal charges have been announced, and the identities of the detained officers remain undisclosed. Security operatives say the investigations will continue until all suspects and collaborators are fully identified and interrogated.
