Osinbajo dismissed the Director General three years after he was appointed by President Buhari.
Daura's dismissal has been speculated to be connected to the invasion of the National Assembly by DSS operatives early on Tuesday, as they prevented lawmakers and journalists from gaining access into the premises in what many believe to be a plot to implement the impeachment of Senate President, Bukola Saraki.
Here are four things to know about Daura:
Daura was born on August 5, 1953, in Daura, in Katsina State, the same place as President Muhammadu Buhari.
Daura received a bachelor's degree from Ahmadu Bello University, Zaria in 1980.
He joined the DSS in 1982.
President Buhari brought Daura out of retirement and appointed him to replace the dismissed Ita Ekpeyong as DSS DG in 2015.
