light-fingered

Having quick, light and nimble fingers.

Having nimble fingers, especially for stealing or picking pockets (pickpocketing), given to thievery or shoplifting.

There is a great quantity of eating and drinking, making love and jilting, laughing and the contrary, smoking, cheating, fighting, dancing and fiddling; […] yokels looking up at the tinselled dancers and poor old rouged tumblers, while the light-fingered folk are operating upon their pockets behind.
