This is the message of Delhi Police to the public in the wake of Mehrauli blast in which a young boy was killed after he picked up a packet, dumped by two motorcyclists, in which explosives were kept.

The city police has appealed to teachers and parents to take the initiative in making children aware of the dangers in picking up objects like toys and attractive packets lying unclaimed on roads.

"Kids are very inquisitive and they tend to fetch objects which could lead to a tragedy. We need the cooperation of parents and teachers," a senior police official said.

A 13-year-old boy, Santosh Kumar, was killed in the blast in a flower market on September 27. He was trying to return the packet, which he thought fell from the hands of the bombers, when the bomb exploded.

"There is a sense of panic these days. I always tell my child not to touch anything which is lying unclaimed and don't accept toys or anything from strangers. Teachers should also tell students about this," Sharmila Khanna, a mother of a five-year-old boy, said.

Police is also warning the public not to pick up any suspicious and unclaimed objects like hand bags, packets, and bicycles, which have been used by terrorists to hide bombs.

The city police has already issued instructions to owners of cyber cafes, in the wake of terrorists using such facilities to send terror mails.
