A lecturer at the University of Nigeria Nsukka allegedly punished her students for not sweeping the classroom by asking them to kneel down and raise up their hands. An observer present where the incident occured reported; 

"This happened earlier today in 3rd year class, department of Microbiology, University Of Nigeria Nsukka.

"No matter how anyone would want to look at it, this is outright insanity, to say the least. How do you mete out this kind of punishment to university students for not sweeping their classroom when we've got non-academic staff who're paid to get stuff like this done???

"If people like this lecturer are not called to order, a time will come when they'd flog and physically abuse students and it will still be swept under the carpet. This is sheer humiliation and totally unacceptable."
