In-spite of stringent punishment under various sections of IPC (Indian Penal Code) and other laws, the sex crime with electronic tools like smart phone, i-pod, tablet and laptop etc. are also frequently reported. These tools are easily misused to record/store obscene picture to motivate the young girls for sex activities. Many such cases are reported against friend, teacher, relative, neighbour and co-worker in the society. In one case, a 9-year old girl was admitted in an English medium school.

On hearing such objection, the parents wanted to change her mind, but the girl- child was rigid in her decision. Further, the parents were anxious to know the actual fact and without hesitation, she narrated the sexual assault on her being committed by the principal. Thereafter, the parents lodged complaints to the police.
