Acting President Yemi Osinbajo

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:

1. He's 65 years old

3. Joined the DSS 36 years ago

He joined the DSS in 1982.

4. He was appointed DG in 2015

President Buhari brought Daura out of retirement and appointed him to replace the dismissed Ita Ekpeyong as DSS DG in 2015.
