Buhari swearn in new icpc boos

I think there may be a slight mistake in your question. The correct phrase is "Buhari swears in new ICPC boss".

For those who may not know, ICPC stands for Independent Corrupt Practices Commission, which is a Nigerian anti-corruption agency.

As of my knowledge cutoff, President Muhammadu Buhari did indeed swear in the new Chairman of the Independent Corrupt Practices Commission (ICPC), Professor Bolaji Owasanoye, on August 5, 2020.
