Buhari appoints new chief security officer

I'm not aware of any recent appointment of a new Chief Security Officer by President Muhammadu Buhari. However, I can suggest some possible sources where you may be able to find this information:

1. Official Government Website: You can check the official website of the Nigerian Government or the Presidency to see if there are any recent announcements or press releases about the appointment of a new Chief Security Officer.
2. News Websites: You can also check reputable news websites in Nigeria, such as Vanguard, Punch, or ThisDay, to see if they have reported on the appointment of a new Chief Security Officer.
3. Social Media: You can also check the social media accounts of the President or the Ministry of Defence to see if they have made any announcements about the appointment of a new Chief Security Officer.

It's important to note that the appointment of a Chief Security Officer is a significant decision that requires careful consideration and approval from the relevant authorities. Therefore, it's likely that any such appointment would be publicly announced and reported by reputable sources.
