Former Central African Republic militia commander, Mahamat Said Abdel Kani will appear before the International Criminal Court (ICC) on Thursday.
He is to face charges of war crimes and crimes against humanity after he was handed over to the ICC on Sunday.
The ICC issued a warrant for the arrest of Mohamat Said Abdel Kani on 7 January 2019.
He was arrested on Sunday in Bria region and surrendered to the court by authorities in the Central African Republic.
Abdel Kani is accused of war crimes and crimes against humanity that he allegedly committed in 2013 in the capital, Bangui, following the overthrow of President François Bozizé.
