An Italian mafia boss, Gioacchino Gammino, has been on the run for decades. Gammino escaped a Rome prison in 2002 and was sentenced to life in jail the following year for murder. He was a member of a Sicilian mafia group and was one of Italy's most wanted gangsters.

He was found in Spain, where he was living under the name Manuel. A Google Street View shot showing a man resembling Gammino standing in front of a grocery shop was key to tracking the fugitive, investigators say.

Sicilian police believed Gammino was in Spain, but it was the photo of him talking to a man outside Manu's Garden, that triggered an immediate investigation. His identity was confirmed when police found a Facebook page of a now-closed restaurant which was located nearby. It had posted photos of Gammino wearing chef's clothes and he was identified by a scar on his chin.

After his arrest, he reportedly told police: "How did you find me? I haven't even called my family for 10 years."
