They were flogged with horsewhips on a cross
A school principal and two others have been arrested in south-western Nigeria for allegedly tying two students to a cross and whipping them for being late.
He confirmed the arrest of the principal, proprietor, usually a reference to the school owner or deputy principal, and a teacher.
A policeman who saw the children being flogged with horsewhips on a cross tried to intervene but was allegedly attacked by the proprietor of the privately owned Metorite Standard School.
The policeman called for back-up and got the proprietor arrested.
