Police say they have arrested nine suspects in the dramatic daytime robbery of a Milan jewelry showroom.

Investigators said nine Italian men were picked up in Milan and Sicily in their investigation of the theft in February at a Damiani jewelry store.

Company chief Guido Damiani thanked police for tracking down the suspects, who were arrested late Monday and early Tuesday. Damiani said police are still looking for the jewels.

Italian news reports said some of the suspects have links to Sicilian Mafia bosses.

Masked thieves drilled a tunnel into a Damiani showroom as employees were preparing for a VIP showing, making off with gold, diamonds and rubies. Damiani never publicly placed a value on the stolen items.
