Venice, April 11 - The grounds of a lavish villa once owned by notorious Veneto crime boss Felice Maniero are being turned into a public park. Part of a swathe of initiatives to turn ex-mafia assets to public use, the confiscated estate in Maniero's home town of Campolongo Maggiore near Venice is being converted by 100 high-school students in their spare time. Former 'Brenta Mafia' chief Maniero, 57, dubbed 'Angel Face', was freed in 2010 after serving more than 20 years in jail. A successful Italian TV series was made by and shown on Sky Italia about his career and lifestyle last year. Maniero, who has since repented and lives in a secret location as a State's witness, complained it was a "travesty" and there was nothing glamorous about a life of crime "which only puts young people in the hands of ruthless Mafia bosses".
