Danish police have been left scratching their heads as they hunt for the vandals who decapitated the Little Mermaid. Few clues have emerged of the second 【M1】______ beheading in 35 years of the famous statue on Copenhagen's waterfront, which has shocked 【M2】______ Danish public and worried tourism officials. Frogmen scouring the harbor near the statue failed to find the Little Mermaid's bronze head and two youth on roller skates seen near the 【M3】______ landmark early on Tuesday morning have not responded police requests to help in the 【M4】______ investigation. 'I am afraid that the latest attack on the Little Mermaid can backfire on our tourism,' said Bernhard Joergensen, director of the Wonderful Copenhagen tourism organization. 'It is important for a tourist city to have a symbol like the Eiffel Tower in Paris and the 【M5】______ London's Big Ben.' Based on the fairytale of Hans Christian 【M6】______ Andersen about the Sea King's daughter that 【M7】______ must wait on her rock for 300 years before entering the world of humans and marrying her prince, the Little Mermaid attracts almost one million tourists a year. The statue was found sever at the neck by a 【M8】______ saw or grinding machine after an anonymous call to a local television cameraman before dawn on Tuesday. Police are working on a theory that the beheading was the work of the same person who sawed a 19th century galleon figurehead at a 【M9】______ naval base in Copenhagen just before Christmas. The severed figurehead was found in the ladies' toilets of a department store on Tuesday, give rise to police suspicions a mentally disturbed 【M10】______ woman may be behind the two decapitations. 【M1】
