More than 100 people were arrested as celebrations marking Barcelona’s second consecutive league title turned violent, police said Monday.
Emergency services also treated 32 members of the security forces and 87 revelers for minor injuries, a police statement said.
It said some 40,000 fans took to the streets of the Catalan capital in northeastern Spain after Barcelona retained its Liga crown on the final day of the season Sunday with a 4-0 home win over Valladolid.
Most incidents took place after midnight when revelers pelted police with bottles, stones and other objects and others destroyed street lamps and benches.
Most of the 104 arrests took place after midnight.
Barcelona made it four league titles in six seasons as they finished the season three points ahead of big-spending arch rivals Real Madrid.
Barca also won the Spanish and European Super Cups in 2010 along with a first ever Club World Cup.
They are also the reigning European champions, a feat they will not repeat this year after being knocked out by Inter Milan in the semi-final.
