Now England have qualified for next year's World Cup, fans looking to travel to Brazil are being warned about the problem of child sex trafficking. A new campaign called 'It's a Penalty' has been set up telling supporters they can be prosecuted back home if they're found to have used the services of a child prostitute. It has the backing of Chelsea footballers David Luiz, Oscar and Ramires.
Sarah de Carvalho - who's a Christian - is leading the campaign and has been speaking to Premier about it.
