Faced with this stark choice, Osagie says she knew no one would believe her word against the lecturer's, so she recorded one of their conversations using a cell phone app.
The audio recording was leaked online and went viral on social media. Osagie says she did not leak it but had submitted it to university authorities before it surfaced online.
The student's allegations, coming amid the conversations around the global #Metoo movement, have now sparked a nationwide conversation in Nigeria about predatory sexual behavior on campuses and bolstered the notion that sexual harassment is a problem women the world over face almost every day.
In the recording, a man can be heard saying that if the student agreed to have sex with him five times, he would improve her grades.
