Smuggling is a major economic activity on the border between Peru and Bolivia, with goods transferred including everything from computers, to clothes, food or fuel
It is estimated that nearly 100,000 people are involved in the illegal cross-border trading, a black-market generating revenues of around $1.5bn a year.
Officials say smuggling generates unemployment because businesses, who pay taxes, cannot match the cost of smuggled goods.
But in one of Peru's poorest regions, Puno, people continue to smuggle their goods even if they risk as much as six years in prison if they are caught.
