All three men were arrested in Rue de l'Eglise in Pétange.
The prosecutor's office has since confirmed that there is a European arrest warrant from France for all three individuals, which means that authorities from Nancy will now take over the case.
In October, a shooting took place in Nancy, and French press connected Nancy to Pétange following a stabbing in August in which two people were seriously injured. However, it has not been confirmed that the affair had anything to do with Wednesday's arrests.
