Police in Brazil's biggest city say they used stun grenades and tear gas to disperse thousands of soccer fans raucously celebrating Argentina's 1-0 World Cup victory over Switzerland.

A Sao Paulo police department press officer says the partying by close to 3,000 people - mostly Argentines - began Tuesday afternoon in Sao Paulo's trendy neighbourhood of Vila Madalena and only ended early Wednesday morning, "when we were called in to disperse the crowd that had gotten too rowdy."

He said stun grenades and tear gas where used after many of the fans started hurling bottles at the police.

The officer said no one was hurt during the incident and no arrests were made.

He spoke on condition of anonymity under police department regulations.
