Italian news agency ANSA said the heist occurred Monday just after an armored truck delivered three cases of money to the courier boat destined for banks and post offices in Venice. ANSA says the bandits took two cases containing banknotes, but left behind the third one, which was filled with coins.
Venice police said no one was immediately available to give more information. The Venice-based armored courier company Civis declined to give details about the heist on one of its boats.
The report said the courier boat had just left the dock when the bandits' boat pulled up next to it.
