Catalan emergency officials say 761 people have been injured as police used force to try to block voting in Catalonia’s independence referendum, according to a BBC report.
The Spanish government has pledged to stop a poll that was declared illegal by the country’s constitutional court.
Police officers prevented some people from voting, and seized ballot papers and boxes at polling stations.
In the regional capital Barcelona, police used batons and fired rubber bullets during pro-referendum protests.
The deadline for voting was 20:00 local time (18:00 GMT), but a Catalan government spokesman said that anyone in the queue at that time would be allowed to vote.
Speaking soon after the deadline, Spanish Prime Minister Mariano Rajoy said he did not acknowledge the vote, adding that Catalans had been fooled into taking part in an illegal vote.
