In a significant move aimed at revitalising Nigeria’s security architecture, President Bola Tinubu has sanctioned the appointment of new Directors-General for two of the nation’s most crucial intelligence agencies: the National Intelligence Agency (NIA) and the Department of State Services (DSS).
The President’s decision marks a strategic shift intended to enhance the operational efficiency of these agencies amidst escalating security challenges across the country.
Ambassador Mohammed Mohammed has been named the new Director-General of the NIA, while Adeola Oluwatosin Ajayi takes the helm of the DSS.

The announcement of these appointments was made through an official statement released by Ajuri Ngelale, the President’s spokesperson.
Ambassador Mohammed Mohammed brings to his new role at the NIA a wealth of experience garnered from an extensive career in the foreign service.
Since joining the NIA in 1995, he has held several key positions that have prepared him for this high-stakes responsibility.
His career trajectory includes notable postings in countries with complex political landscapes, such as North Korea, Pakistan, and Sudan.
These assignments, alongside his tenure at the State House in Abuja, have equipped him with the diplomatic acumen and strategic foresight necessary to navigate the intricacies of national and international intelligence work.
A 1990 graduate of Bayero University in Kano, Ambassador Mohammed’s educational background has also played a pivotal role in shaping his career.
His academic and professional experiences culminated in his promotion to the rank of Director within the NIA.
Before his recent appointment, he served as the head of the Nigerian mission to Libya, where he demonstrated exemplary leadership in a region fraught with instability.
His return to Nigeria to lead the NIA is seen as a move that could revitalise the agency’s approach to intelligence gathering and international relations.
Adeola Oluwatosin Ajayi’s Rise to Leadership in the DSS
The newly appointed Director-General of the DSS, Mr. Adeola Oluwatosin Ajayi, is no less distinguished.
His career with the DSS has been marked by a steady rise through the ranks, reflecting his deep understanding of Nigeria’s security dynamics.
Mr. Ajayi’s experience spans various critical postings across the country, where he has served as State Director in several states, including Bauchi, Enugu, Bayelsa, Rivers, and Kogi.
His ability to manage diverse security challenges in these regions has earned him a reputation as a diligent and capable officer.
Mr. Ajayi’s most recent position as Assistant Director-General of the DSS further underscores his readiness for this new role.
His promotion to the top of the DSS hierarchy is expected to bring a fresh perspective to the agency’s operations, particularly in its counterintelligence and counterterrorism efforts.
Given the current security challenges Nigeria faces, his leadership will be crucial in strengthening the country’s internal security apparatus.
The appointments of Ambassador Mohammed and Mr. Ajayi follow the recent resignations of the former heads of the NIA and DSS.
President Tinubu’s choice of these two seasoned professionals signals his administration’s commitment to addressing Nigeria’s security concerns with renewed vigour and strategic direction.
The President has expressed confidence that the new Directors-General will leverage their vast experience to reposition the NIA and DSS for greater efficiency and effectiveness.
In his statement, President Tinubu emphasised the importance of enhanced collaboration between the NIA, DSS, and other security agencies, particularly under the guidance of the Office of the National Security Adviser (ONSA).
This call for cooperation is seen as a critical element in the administration’s broader strategy to tackle the multifaceted security challenges confronting the nation.
As the new Directors-General assume their duties, they face the formidable task of steering their respective agencies through a period of intense scrutiny and high expectations.
The President’s directive to “work assiduously” underscores the urgency of the situation, as Nigeria continues to grapple with issues ranging from terrorism and insurgency to kidnapping and organised crime.
The success of Ambassador Mohammed and Mr. Ajayi in their new roles will be measured by their ability to implement strategic reforms, foster inter-agency collaboration, and deploy innovative intelligence-gathering techniques.
Their leadership will be crucial in restoring public confidence in Nigeria’s security apparatus and ensuring that the NIA and DSS are well-equipped to address both current and emerging threats.
In his closing remarks, President Tinubu extended his gratitude to the outgoing Directors-General for their service to the nation, wishing them success in their future endeavours.
As Nigeria turns a new page in its intelligence and security operations, the nation watches with anticipation to see how these appointments will influence the course of national security.
