David Mwole Kimaiyo remains one of the most recognisable figures in Kenya’s policing history, having become the country’s first Inspector General (IG) of the National Police Service after the promulgation of the 2010 Constitution.
He was born on July 1, 1960 and rose rose through the ranks of the Kenya Police over a career spanning more than three decades before taking over the newly created constitutional office in December 2012.
His appointment marked a major shift in Kenya’s security sector, as he became the first police chief to undergo a competitive recruitment process by the National Police Service Commission and parliamentary vetting before assuming office.
According to records obtained by DNK-International
Kimaiyo joined the Kenya Police in the early 1980’s after undertaking police training and steadily climbed the ranks through operational and administrative assignments.
His professionalism earned him a place in the elite Presidential Escort Unit, where he served as Commander between 1999 and 2002, protecting retired President Daniel arap Moi during the final years of his administration.
His tenure at the Presidential Escort Unit (PEU) established him as one of the country’s most trusted security officers.
After leaving the Presidential Escort Unit, Kimaiyo became Commandant of the General Service Unit (GSU), one of Kenya’s most specialised police formations.
He later served as Director of Police Operations and headed the Kenya National Focal Point on Small Arms and Light Weapons, gaining extensive experience in internal security, counter proliferation and police management before being selected as Inspector General.
Academically, Kimaiyo built one of the strongest educational profiles among senior Kenyan police officers.
He holds a PhD in Sociology and Criminology from the University of Nairobi, a Master of Science in Criminology and Criminal Justice from the University of Leicester in the United Kingdom, a Bachelor of Arts in Criminology and Criminal Administration from the University of South Africa (UNISA), and Bachelor and Master of Theology degrees from Beacon University Institute of Ministry.
His academic background has often informed his commentary on crime, governance and security reforms.
When he assumed office on December 24, 2012, Kimaiyo inherited a police service undergoing major constitutional reforms aimed at improving accountability, professionalism and public confidence.
His administration oversaw continued implementation of police reforms, recruitment of officers, efforts to modernise policing systems and campaigns against illicit small arms.
He also pushed for greater coordination among Kenya’s security agencies at a time when terrorism posed an increasing threat.
However, his tenure was overshadowed by a series of devastating terrorist attacks, most notably the 2013 Westgate Shopping Mall attack in Nairobi, in which at least 67 people were killed.
The attack exposed operational weaknesses, poor inter-agency coordination and communication failures among security agencies.
Although several investigations pointed to broader institutional shortcomings rather than individual blame, Kimaiyo faced sustained criticism over the police response and growing insecurity in the country.
Continued Al-Shabaab attacks in Mandera, Wajir and other parts of northern Kenya further intensified pressure on his leadership.
In December 2014, Kimaiyo announced his early retirement, saying he had informed President Uhuru Kenyatta that he was stepping down for personal reasons.
His exit came amid heightened public criticism following deadly Al-Shabaab attacks in Mandera, although many Kenyans continued to associate his resignation with the mounting pressure that had followed the Westgate siege and subsequent security failures.
Supporters credit Kimaiyo with helping lay the institutional foundation for the office of Inspector General, strengthening police reforms initiated under the new Constitution and promoting professional policing standards.
Critics, however, argue that his tenure struggled to effectively address terrorism, public confidence in the police and coordination among security agencies during national emergencies.
After retiring from active police service, Kimaiyo largely withdrew from frontline public office and ventured into farming,and tried his hand in politics by vying for the Senatorial seat in 2022 in his home region of Elgeyo-Marakwet.
He has invested in agriculture while also remaining active as a security consultant and analyst, frequently offering expert opinions on terrorism, police reforms, election security and national security matters through the media and public forums.
Kimaiyo has also shown an interest in elective politics.
Word has it that he’s contemplating vying for the gubernatorial seat in Elgeyo Marakwet in 2027.
Though,Kimaiyo himself has not confirmed his declaration that he intends to contest in the next General Election, leaving his future political ambitions open to speculation.
His political engagements have generally focused on community development and leadership discussions rather than sustained party politics.
Throughout his career, Kimaiyo became known for his disciplined communication style and repeated calls for professionalism within the National Police Service.
Among his memorable remarks was his insistence that police officers must operate within the Constitution while remaining firm against criminals.
Upon announcing his retirement, he thanked officers for their dedication and urged them to “continue doing the good work and even double their efforts in the protection of this country and its citizens.”
Kimaiyo’s legacy continues to generate debate.
To many, he was a highly educated police commander who helped usher in constitutional policing reforms during a difficult transition period.
To others, his tenure will always be remembered for the security challenges that defined his time in office, particularly the Westgate attack and subsequent terror incidents.
Even so, his journey from a career police officer and presidential escort commander to becoming Kenya’s inaugural Inspector General remains one of the most significant chapters in the country’s modern police.
Kimaiyo is also a senior member of Africa Inland Church (AIC).
