Catalonia referendum latest: Spain apologises for police violence
Catalonia has received an apology from the Spanish official Enric Millo (R) after Sunday's violence
The violent crackdown injured nearly 900 as batons and rubber bullets were used against protestors and people trying to cast their vote.
The Spanish government has consistently argued the referendum was illegal and the vote was banned by the country's top constitutional court.
But in a televised interview today, Madrid's representative in Catalonia, Enric Millo, said: "When I see these images, and more so when I know people have been hit, pushed and even one person who hospitalised, I can't help but regret it and apologise on behalf of the officers that intervened."
Catalan officials have said they could declare independence as early as Monday.
