Academic institutions in West Africa have increasingly been facing allegations of sexual harassment by lecturers. This type of abuse is said to be endemic, but it's almost never proven.

Female reporters were sexually harassed, propositioned and put under pressure by senior lecturers at the institutions - all the while wearing secret cameras.
