Frank Mba, a Deputy Inspector-General of Police (DIG), and seven other DIGs have retired from the Nigeria Police Force following recent changes in the leadership structure of the force.
The retirement follows the appointment of Tunji Disu as the new Inspector-General of Police by President Bola Ahmed Tinubu, replacing Kayode Egbetokun.
Before his appointment, Disu served as an Assistant Inspector-General of Police (AIG), a rank below DIG.
In a statement on Friday, the Police Service Commission said seven AIGs have been promoted to the rank of DIG after undergoing oral interviews and written examinations conducted on the same day.
The newly promoted DIGs are Zachariah Fera Achinyan, Zango Ibrahim Baba, Isyaku Mohammed, Margaret Agebe Ochalla, Mohammed Abdul Sulaiman, Kenechukwu Onwuemelie, and Umar Shehu Nadada.
According to PSC spokesperson Torty Njoku Kalu, Fayoade Adegoke, who was promoted to the rank of DIG in February 2026, will now join the Force Management Team.
Mba joined the police in May 1992 as a cadet inspector and served in several key positions during his career. A native of Ezimo in Udenu LGA of Enugu State, he emerged as the best graduating cadet inspector in academics at the Nigeria Police Academy in Kano.
In June 2023, the Police Service Commission approved his appointment as DIG to replace John Amadi as the most senior officer from the South-East in the police management team. He was promoted to DIG three months after being elevated to the rank of AIG.
During his service, Mba served as commissioner of police in Ogun State and commissioner of police in charge of the Border Patrol Force at the force headquarters. He also held operational commands as area commander in Ajah and Festac in Lagos and served two terms as the force spokesperson.
He studied law at the University of Lagos and was called to the Nigerian Bar in 2002. He later earned a master’s degree in law with distinction from the University of Dundee in Scotland.
