Eya, the 10-year-old girl abducted by her father and found Friday in Denmark, was joined by her mother. The case was solved thanks to cooperation between European police forces, as recalled by the public prosecutor of Grenoble, Eric Vaillant.

But how exactly does this cooperation work? Europe 1 takes stock. How could little Eya be found so quickly in Denmark? Investigators quickly spotted her thanks to the cooperation of European police. This is actually based on the Schengen Agreement.
