Barcelona sees a sixth night of violence over rapper jailed for insulting the monarchy on Twitter

Protests have raged for a sixth night in Barcelona with masked demonstrators throwing bottles, firecrackers and other missiles at police during a rally in support of a jailed rapper.

As in previous days, Sunday’s protest began peacefully but descended into violence as night fell, with a crowd of several hundred people marching to the National Police headquarters. 

Protesters chanted ‘Freedom for Pablo Hasel’ in support of a little-known rapper jailed for nine months and fined over his incendiary tweets and lyrics.

Catalan police were pelted with rocks, bottles, bins and firecrackers for half an hour before they moved in to clear the street in front of the station. 

Shops in Barcelona’s city centre once again fell prey to vandals who smashed their windows, while some protesters set up barricades on the city’s Las Ramblas boulevard.

Sunday’s protest was calmer than those of previous nights which escalated into violent clashes.

Earlier in the day, graffiti artists painted a mural depicting Spain’s King Felipe VI and his father, former king Juan Carlos I, alongside dictator Francisco Franco, who ruled Spain from 1939-1975, in solidarity with Hasel.

Seven people were arrested on Sunday, part of the more than 100 to have been detained in Barcelona and other cities in Spain’s northern Catalan region since Tuesday.

Angry demonstrations erupted after police detained 32-year-old Hasel and took him to jail to start serving a nine-month sentence in a highly contentious free speech case.

Unrest on Saturday saw protesters smash their way into shops along Barcelona’s glitzy Passeig de Gracia shopping avenue, looting stores such as Nike, Versace, Tommy Hilfiger, Hugo Boss and Diesel.

Known for his hard-left views, Hasel was handed a nine-month sentence over tweets glorifying terrorism and videos inciting violence. 

The court ruling said freedom of expression could not be used ‘as a “blank cheque” to praise the perpetrators of terrorism’.
