According to a report by Premium Times, the new DIGs, who were elevated from assistant inspectors-general, are Usman Tilli Abubakar, who joined the police from Kebbi State in February 1986; Abdulmaji Ali, who joined the police from Niger State in February 1986; Taiwo Frederick Lakanu, who joined the police from Lagos State in February 1986 and Godwin Nwobodo, who joined the police from Enugu State in 1984.
The remaining two new DIGs who were elevated from the rank of police commissioners are Ogbizi Michael, former Abia State police commissioner, and Ibrahim Lamorde, a former chairman of the Economic and Financial Crimes Commission (EFCC) who hails from Adamawa State.
Mr Lakanu was the Force Secretary until his appointment.
Their respective portfolios would be announced later on Monday by the Police Service Commission.
Their elevation comes a day after Mr Adamu retired seven DIGs who were his senior in order to pave way for the constitution of a new management team with whom he could work comfortably.
The affected officers were Maigari Dikko, the DIG in charge of finance and administration and Habila Joshak, the DIG in charge of operations.
The remaining five DIGs are Emmanuel Inyang, information and communications technology; Agboola Oshodi-Glover, logistics and supply; Mohammed Katsina, research and planning; Sani Mohammed, training and development; and Peace Ibekwe-Abdallah, federal criminal investigation and intelligence.
The seven DIGs and eight assistant inspectors-general were identified as having joined the police before Mr Adamu, who was appointed on January 15 after the former IG Ibrahim Idris was retired as he attained 60 years.
The seven police chiefs’ departure was in furtherance of the convention that recommends the retirement of senior police chiefs when an officer junior to them in service or lower in rank is appointed to lead the institution.
When Mr Idris was appointed IG in 2016, more than 20 DIGs and AIGs were compelled to retire from service to enable him constitute his management team.
Mr Adamu has now followed the tradition, which has been criticised as wasteful and demoralising because of huge resources the nation had spent on the vast knowledge the senior officers had acquired over the years.
