I was pick-pocketed from my front trouser pocket in Saint Petersburg last year when boarding a Metro train.

The platform was ridiculously busy and there was a group of people pushing everyone onto the train with some force. In the mayhem there wasn't much you could do as there were so many people being pushed onto the train.

During that moment someone managed to removed all of my cash from my trouser pocket. I didn't notice until I got off the train minutes later.

At first I though the crowd of youths were helping people to board the train, but they were a gang of pickpockets who used the mayhem to their advantage.
