The Serbian president has reportedly been charged after breaking anti-hooligan laws.
The AP says that Boris Tadic was reprimanded after he opened a bottle of champagne in the VIP area of a football stadium to celebrate Serbia's qualification for the 2010 World Cup.
The police filed charges against various officials, including Tadic and the sports minister Snezana Markovic-Samardzic, for "violating the law preventing violence and indecent behaviour at sporting matches".
The law prohibits the sale or consumption of alcohol at Serbia's football stadiums and is aimed at reducing violence.
Tadic said that he will pay a fine if he is found guilty.
