With extraordinary access to the closed world of Europe's Gypsies, as well as covert footage, film-maker Liviu Tipurita examines how Romanian Gypsy children across the continent are forced to beg and steal, often for the profit of organised crime.
Here he observes a Gypsy girl in Milan, Italy.
This World, Gypsy Child Thieves, will be broadcast on Wednesday 2 September at 1900 BST on BBC Two.
