The former Minister for Education alleged that it was President Muhammadu Buhari who instructed the IG of Police to detain her and other members of the BBOG group.
It was gathered from Oby Ezekwezili’s tweets that she is being detained at the Unity Fountain, adding that police officers “built an impregnable wall” and “locked her in”. 
She stated that Officer Tina Ishaya, one of the police officers detaining her, refused to let her out of the wall.
