BBC reporters went undercover and succeeded in exposing a number of lecturers from Nigerian and Ghanaian universities who subject students to sexual harassment.
The full video will be aired later tonight but the short one released shows Unilag senior lecturer Dr Boniface Igbeneghu and University of Ghana lecturer Dr Paul Kwame Butako sexually harassing undercover reporters who they thought were students.
Nigerians were shocked by the story because Dr Boniface is a pastor in his 50s yet sexually harassed the undercover reporter he thought was a 17-year-old prospective student.
Also, Dr Butako's behaviour shocked Ghanaians because he is a married man.
This exposé (read here) has elicited Twitter reactions as people await the full video.
