Spanish riot police burst into a school in Girona in northern Spain seizing ballot boxes and voting papers. It was just one of around 92 polling stations shut down by National Guard officers.
Throughout Sunday officers carried out raids across Catalonia to prevent a banned independence referendum.
Wherever the police went they were met with resistance from Catalan administrators over seeing the vote.
Outside polling stations at least 750 people are believed to have been injured as police hit would-be-voters with batons and fired rubber bullets.

The force used by riot police have beencondemned internationally but described by the government in Madrid as proportionate.
Despite the police action hundreds-strong queues of people formed in cities and village throughout the region to cast their ballots.
While the national Civil Guard went in hard on demonstrators the regional police reportedly made little attempt to remove people trying to vote.
