RPF — Pickpocketing at nizamuddin railway station

I was at platform no. 7 at nizamuddin railway station to board train no. 12248. The moment i boarded the train i found the zipper of my hand bag open and by the time i could make out that my purse containing cash, credit card and some jewelry was missing the train started. To whom and how should i complain. The cctv footage can be of help to trace the thief. Time 15:35, date 8th april, 2017. Pnr no. [protected]. Mrs pratibha khandelwal.
