The incident sparked numerous reactions with the National Association of Graduate Teachers calling for a severe sanction to be meted out to Akakpo to deter others from engaging in the same conduct.
A court has now sentenced him after being prosecuted for the bloody act.
According to Citinewsroom.com, the presiding judge, His Honour Joseph Ofosu said that the four-year jail term was necessary to serve as a deterrent to other students.
