Polytechnic students under the umbrella of the National Association of Polytechnic Students (NAPS) have threatened to occupy the Presidential Villa, Abuja. The students also threatened to shut down all polytechnics, colleges of technology and allied institutions across the country if President Muhammadu Buhari fails to sign the Higher National Diploma/Bachelor of Science (HND/Bsc) Dichotomy Bill into law within 14 days.
