More than 600 young people took part in protests in Barcelona on Saturday, the Spanish newspaper La Vanguardia reports.
About a dozen stores were looted, and protesters threw rocks and fireworks at police, set fire to garbage cans and built barricades out of parked vehicles. Emergency services extinguished more than 30 small fires.
Inspired by France
The protest was organized via social media and was reportedly directed against rising housing costs and in support of demands for better living conditions.
"We will not let this go unpunished," Barcelona Mayor Jaume Collboni said at a press conference, according to La Vanguardia.
The riots are believed to have been inspired by similar protests in France.
