Denver Broncos will face Seattle Seahawks in the Super Bowl this Sunday, the National Football League's yearly championship and one of the most watched sporting events in America.
New York and New Jersey are hosting the game for the first time and hundreds of thousands of visitors are expected to travel to the region.
But officials say there is a dark side to the event - sex traffickers who want to exploit the occasion for profit.
