Authorities in Sao Paulo, Brazil, are investigating an incident in which a man drew a gun during a protest against the high cost of the World Cup.
Police say it happened Monday as dozens of protesters gathered on Avenida Paulista, the city's main avenue and a popular destination for tourists.
Sao Paulo civil police say they are investigating whether the man in civilian clothes was a police officer and whether he actually fired the gun that he waved in the air. Local media say that shots were heard and that riot police fired stun grenades to disperse the protest.
