Four protesters have been arrested after glueing themselves together and spraying paint on a building in central London, the Metropolitan Police said.

       Palestine Action activists blockaded a building in Holborn where the Israeli weapons company Elbit Systems has an office, the campaign group said on Twitter.

       Footage showed the entrance of 77 Kingsway covered in red paint as the four demonstrators, their arms locked together in cylinder tubes, chanted: "Shut Elbit down".

       Two men and two women were arrested on suspicion of criminal damage and assault, according to Scotland Yard, which said a member of staff at the building was assaulted.

       A police “de-bonding team” was deployed to help remove the protesters, who were also pictured letting off coloured smoke flares.

       Palestine Action tweeted: "If this were Palestine, this smoke might well be Elbit-made tear gas used on the Palestinian people.

       "Palestine is being choked by the warmongers at Elbit - and our place in the fight to #FreePalestine is to join the resistance and #ShutElbitDown."

       Elbit Systems was contacted for comment.
