The mayor of Venice is among 35 officials arrested on suspicion of embezzling money meant for the city's flood defences.
The project, to build new mobile barriers to protect the city from flooding, was due to be completed this year but has been repeatedly delayed.
Investigators are looking into allegations that 20m euros ($27m, £16m) in public funds was sent to foreign bank accounts and used to finance political parties, according to reports.
Alan Johnston reports.
