The Personal Chief Security Officer to Buhari was supposed to retire but his service has been illegally extended to 2023. He's a nephew to Mamman Daura. Was only a CSP in 2015 but was rapidly promoted to Commissioner of Police in just 4 years. That's from CSP to ACP to DCP to CP! 
More context: Abdulkarim Dauda, Buhari's PCSO, is the son of Mamman Daura's brother. Recall that Mamman Daura's father, called Dauda Daura, is Buhari's half-brother from the same father. (Mamman Daura is Nigeria's de facto president for whom Abba Kyari acts.)Nepotism on steroids!
My friends from Daura just called to say that Abdulkarim Dauda is actually Mamman Daura's blood brother and Buhari's nephew. That means, like Mamman Daura, Buhari is his uncle.
