The 19-year-old French girl was lured to the monument on the proviso of a 'date' set up through Facebook. She responded to messages from who she thought was a 17-year-old Tunisian boy and initially met him close to her home in the Paris suburbs. Last Sunday evening she turned up for another date where she expected to have a picnic with the boy at the Champs des Mars, the park where the Eiffel Tower is, and was attacked.

A source close to the case, said: “It was a warm night, and she expected to eat strawberries and grapes, and to drink Coke, but then the attack took place.” The woman was dragged under a bush behind where a blanket had been laid out. She was then assaulted by three men who then gagged, beat her up and tied her up.

The victim, who cannot be named for legal reasons, is said to have recently run away from her mother’s home in the Paris suburbs. She was only found when a couple who were jogging early on Monday morning heard the victim making a muffled sobbing noise. They raised the alarm after finding her in deep shock, naked and crying.

Police then used computer data to quickly trace the three men to a hotel in the 18th arrondissement of Paris. They were caught there just before they tried to flee to Germany on Monday. None of them had any official papers and all claimed they were 17 year olds from Tunisia and were seeking asylum. However, early checks suggest they are likely to be a lot older and possibly from Algeria.

The source, said: “An enquiry is underway to try and work out exactly who they are, and what they were doing in France.” All the men deny rape, saying they were involved in a “consensual adult relationship” with the woman. The three men, who also cannot be named for legal reasons, have been remanded in custody as prosecutors and police continue a rape investigation. Their victim is currently in the care of social services.
