A group of Italians pretending to be doctors has been arrested for peddling a "miracle cure" for cancer and other diseases, which turned out to be nothing more than ordinary tap water, The Telegraph reports.

They sold flasks and vials of the 'White Light' water for up to 200 euros ($263), claiming it had been collected from "holy springs" at pilgrimage sites like Lourdes in France, Fatima in Portugal, and Medjugorje in Bosnia and Herzegovina. The ringleader was Enza Maria Ciccolo, a 71-year-old biologist, according to Rai Giornale Radio.

Police arrested 39 people in Milan, Venice, Bari, and Ancona, and seized 4,000 flasks of the water. The men have been accused of fraud, conspiracy, personal injury and wrongful practice.
