Fans riot at Brazil World Cup stadium, police forced to fire grenades and smoke bombs

Brazilian police were forced to fire percussion grenades and smoke bombs in a bid to stop football fans rioting after the end of the Ceara state championship final on Sunday.

A 2-2 draw in the second leg was enough for Fortaleza to beat their city rivals Ceara, a side they had defeated 2-1 in the away leg a week earlier.

In a dramatic tie, Fortaleza looked to have secured the victory when they scored in the first half to take a 3-1 aggregate lead. Remarkably Ceara came fighting back in the final moments, scoring in the 81st minute to make it 3-2 before netting a 90th minute dramatic equaliser to all but send the game into extra-time.

Fortaleza attacker Cassiano had other ideas, taking the home side up the other end to score the winner just two minutes later, causing the supporters to celebrate riot wildly on the Estádio Castelão pitch – a stadium used during the 2014 World Cup.

‘The stadium's infrastructure wasn't made for Brazilian football fans,' said Lt Col Aguinaldo to Brazilian outlet Globoesporte – judging by the above clip he's not wrong.

‘It's easy for fans to invade the field like this. Holding back a rebellious mob is difficult,' he continued.

If you're wondering why there are so many empty seats for the supporters to rip up and throw at each other, it's because Fortaleza normally play their home games at the Alcides Santos Stadium with a capacity of just 7,000.

In stark contrast to the 63,000-seater Estádio Castelão, a ground the home nation played two games at during the World Cup, there's always going to be one or two spare seats right?
