An Indian school official has apologised after a bizarre set of images went viral showing students wearing cardboard boxes on their heads.

The images were taken during a chemistry exam at Bhagat Pre-University College in Haveri, Karnataka state.

They showed students wearing boxes, cut open on one side, to prevent them from being able to copy other people's work.

A junior college administrator has spoken publicly and apologised to district officials for the incident.
