Pune, Oct 19 (IPS) - Fourteen-year-old Priti Pyne was returning from school in Basra village in South 24 Parganas, West Bengal, when she and a friend came across a cold-drink seller selling an attractive-looking drink. The moment the girls sipped it, however, they felt dizzy. When they woke up, it was on a Delhi-bound train at Sealdah station in Kolkata. With the help of other passengers, the girls managed to get off the train.
