This video shows how bold the petty thieves in Rio de Janeiro are.
In the clip a group of youngsters target innocent bystanders as they walk through the busy streets.
The thieves use a number of methods, including snatching items while they’re riding bikes and reaching into coach windows when the victim is distracted.
But their main tactic seems to be grabbing valuables from pedestrians and then running away.
This works for them a lot of the time because the victims are usually taken by surprise.
But it doesn’t always end in success.
In the clip one of the youngsters is punched by a man after he attempts snatch a chain from around a woman’s neck.
The video was filmed in March, a few months before the Olympic Games started.
