The recent inappropriate activities that were carried out as part of student orientation programmes at two tertiary institutions show that the authorities have failed to make clear their stand on this issue.

In one incident, some students from the National University of Singapore stripped naked in the water at Siloso Beach in Sentosa as part of unofficial orientation activities (NUS probing alleged stripping at beach game; June 21).

In another, a female student was seen performing a sexually suggestive dance in front of a male student at a Ngee Ann Polytechnic co-curricular activity camp (Ngee Ann Poly to counsel students involved in lap dance video filmed during CCA camp; June 21).

It is not the first time sexualised activities in schools have been reported.

Obviously these senior students lack EQ, or emotional quotient, and possess dubious IQ despite being able to reach tertiary level.

Just like the recent death of a Singapore Civil Defence Force full-time national serviceman during illegal activities to mark the operationally ready date of a batch of trainees, these incidents at the two educational institutions are examples of poor supervision and lackadaisical enforcement by the top leadership.

I hope, once and for all, the message can be sent to these recalcitrant black sheep in our institutions that they will be severely punished and expelled, or feel the full force of the law.
