Fans celebrating FC Barcelona's 20th Primera Liga title caused violent scenes in the early hours of Monday morning.

Over 100 people were arrested for public order offenses after the celebrations got out of hand.

The night began well with Barca's 4-0 win over Valladolid and from 9pm onwards, over 40,000 supporters began congregating the famous "Fuente de Canaletas" in the Ramblas, the traditional site of Barcelona's celebrations.

Events were peaceful with signing, chanting and other celebrations until after midnight when some more radical supporters tried to climb a facade of a building and tear down a tapestry.

Meanwhile others began to attack and destroy bus stops and rubbish containers in the area and when the police reacted events developed into a chaotic street fight.

The night ended with 104 arrests for destroying public property and violence against the police force.
