Swiss prosecutors say a painting seized in Serbia has been confirmed as a stolen masterpiece by French impressionist Paul Cezanne.

Zurich prosecutors said Thursday that the E.G. Buehrle Foundation certified that the painting is Cezanne's "The Boy in the Red Vest."

The painting was worth 100 million Swiss francs ($109.6 million) when it was stolen along with three other works from the private Buehrle collection in 2008.

Two paintings by Claude Monet and Vincent van Gogh were recovered shortly after the heist. The whereabouts of the fourth, by Edgar Degas, is still unknown.

Serbian police said Thursday three people were arrested in connection with the robbery.
