FULL LIST: Frank Mbah, Other DIG Likely To Retire After Tunji Disu ‘s Appointment As IG

President Bola Ahmed Tinubu has approved the appointment of Assistant Inspector General of Police, AIG Tunji Disu, as the Acting Inspector General of Police.

Disu, who is currently the head of the FCID Force Annex Ikoyi in Lagos, succeeds Mr Kayode Egbetokun as the Inspector General of Police.

His appointment followed the resignation of Kayode Egbetokun from the apex office of the nation’s police force.

The immediate past IG tendered his resignation, citing pressing family considerations.

Appointed in June 2023, Egbetokun was serving a four-year term scheduled to conclude in June 2027, in line with the amended provisions of the Police Act.

Disu has extensive operational and intelligence experience as a police Officer serving in several parts of the Country.

He was also a former Head of the Lagos State Government’s Internal Security arm known as Rapid Response Squad (RRS).

Several concerns were raised on social media regarding his appointment while holding the rank of AIG, as it effectively bypassed eight more senior DIGs currently in office.

Critics argued that the move disrupted the traditional hierarchy of the Nigeria Police Force.

Until his appointment, Disu was the Assistant Inspector-General of Police (AIG) in charge of the Force Criminal Investigation Department Annex, Alagbon, Lagos, a position he assumed in February 2026.

In Nigeria, it is an established practice for senior police officers to retire when a junior colleague in the hierarchy is appointed Inspector-General of Police.

Nigeria has witnessed several incidents where high-ranking officers in the Army, Air Force, and Navy have bowed out of service following the appointment of their subordinates as Force Chiefs.

Although not legally mandatory, this tradition reflects the Force’s deep-seated respect for seniority and its commitment to maintaining organisational stability.

This tradition, rooted in military hierarchy, often necessitates the simultaneous retirement of numerous generals and senior officers to preserve the sanctity of the chain of command.

In this report, TVC News identifies the eight senior DIGs whose mandatory retirements are necessary for AIG Tunji Disu to assume full leadership of the Nigeria Police Force.
