Protests rock Spain for 3rd night in a row after rapper jailed for tweets insulting king & praising terrorist groups (VIDEOS)

Rallies protesting the arrest of a rapper convicted of insulting the monarchy have continued across Spain for a third straight night. One woman reportedly lost an eye and more than 50 people were detained at demos a day earlier.

Valencia saw some of the worst violence on Thursday, where demonstrators could be seen clashing with riot police in footage posted to social media, while a聽helicopter聽appeared to be monitoring the protests from above.聽

Multiple injuries were reported amid the clashes in the eastern Spanish city, while some protesters appeared to hurl stones and bottles at officers.

In Barcelona, which saw the first protests two days ago, further violent clashes broke out on Thursday, as bins, bikes and a building were set on fire.聽

Protests in the Catalonian capital focused on the Ministry of the Interior, where a heavy police presence was in place, with helicopters also deployed. Barricades have also been erected in Barcelona and the windows of Spanish newspaper El Peri贸dico have been smashed,聽according to聽El Pais.

The trouble follows the arrest of rapper Pablo Hasel on Tuesday in the Catalan University of Lleida, where he and dozens of his supporters had barricaded themselves inside. The artist was held after failing to report to prison for a nine-month sentence handed to him for glorifying terrorism and accusing Spain鈥檚 disgraced former King Juan Carlos of corruption in a series of tweets.

Hasel鈥檚 detention has raised major questions about Spain鈥檚 free speech laws and one of the country鈥檚 main political groups has now thrown its weight behind a campaign to pardon the rapper.

On Thursday, the far-left Podemos party, which props up Spain鈥檚 coalition government, filed an official request with the Ministry of Justice for Hasel to be pardoned, because of his 鈥渦njust鈥 detention.

The conservative PP party, meanwhile, has slammed Podemos for not condemning the protests after tweets from its party members appeared to allege police had used unnecessary force against demonstrators.
