Brazilian Police Tell World Cup Tourists Not To Scream If They're Mugged

    Fans are being given flyers telling them to "not yell or argue" when confronted by armed robbers.

    If you're heading to the World Cup in Brazil this summer and you encounter any armed criminals, remember to keep your mouth shut.

    Brazilian police and armed forces are staging a huge counter-terrorism and anti-crime operation to keep the 600,000 expected foreign visitors safe.

    Brazil is braced for more protests, following the riots that accompanied the Confederations Cup in the country last year, pictured here.
