Football officials in the Brazilian city of Rio de Janeiro have called for urgent action to prevent further damage to the city's famous Maracana stadium after it was broken into, BBC reports.
The city's football federation said windows were smashed and items stolen.
The stadium, used in the recent Olympics, is at the centre of a dispute over who should maintain it.
It is owned by Rio de Janeiro's state government which has been hit hard by Brazil's deep economic crisis.
The stadium underwent costly modernisations for the 2014 World Cup and the 2016 Olympic Games but has lain empty as clubs and authorities argue over who should manage it.
The federation said "the worries over the present and the future of the stadium are only increasing".
