American philanthropist Jason Buzi will not be allowed to stage his quirky @Hidden Cash treasure hunt in Paris at the weekend, police said Wednesday. The distribution of money in public is forbidden by French criminal law and punishable by six months in jail and a 30,000 euro ($40,000) fine, police said in a letter to Buzi, a wealthy real estate investor. The Internet-driven treasure hunts have participants track down the envelopes using clues posted on Twitter with the handle @HiddenCash.
