Denmark's most iconic landmark was subjected to an overnight act of vandalism as part of a whaling protest.
The statue of The Little Mermaid in Copenhagen, a key tourist attraction, was coloured red, and a message was written on the beach beside it.
The message read: "Denmark, defend the whales of Faroe Islands."
This refers to the tradition of 'grindatrap' in the North Atlantic archipelago, which sees whales slaughted after they are boxed into a body of water like a fjord.
Copenhagen police confirmed they were investigating.
This is not the first time the statue has been vandalised. The long-suffering mermaid had her head stolen in 1964, 1984 and 1998.
She's been pushed into the sea on numerous occasions, and in 2004, protestors opposing Turkey's application to join the European Union covered her with a burqa.
