From a Wall Street Journal story by Margherita Stancati headlined “Italian Police Arrest Most-Wanted Sicilian Mafia Boss”:

ROME—Italy’s Carabinieri military police have detained the country’s most notorious fugitive mafia boss, who had been on the run for 30 years, dealing a blow to one of the world’s most storied crime syndicates.

Matteo Messina Denaro was in a private hospital on the outskirts of the Sicilian city of Palermo when Carabinieri swarmed the area and captured him on Monday morning, the Carabinieri said.
