Celebrations marking Atletico Madrid's King's Cup win turned violent in the early hours of Saturday as hundreds of revelers faced off with riot police near Neptune fountain in the Spanish capital.

Atletico's jubilant fans spilled onto the streets of Madrid to celebrate their first victory in 14 years over their bitter city rivals, but scuffles soon broke out after some supporters began hurling bottles and other items at police.

A car that had been torched could be seen on a street next to the iconic Neptune fountain.

Baton-wielding riot police dispersed the large crowds by charging at them, while fire-fighters soon arrived at the scene to extinguish the torched vehicle.

Atletico Madrid stunned city rivals Real to win their 10th King's Cup when Miranda's extra-time header secured a 2-1 comeback.
