I caught him pick-pocketing on the crowded subway yesterday.

During the crowded festival, pick-pockets worked quickly among the stalls.

He pick-pockets tourists on the subway, then disappears into the crowd.

While boarding the crowded train, Maria was pick-pocketed and didn't notice until she reached her stop.

I lost my watch to a cunning pick-pocket on the crowded subway.

She tried to pick-pocket the tourist's wallet on the crowded platform, but a vigilant commuter noticed and raised the alarm.
