Italian police are investigating the chaos surrounding handling of luggage at Fiumicino Airport in Rome.
Thousands of passengers have suffered delays
Thousands of pieces of baggage have gone astray during the heaviest travel weekend of the year.
More than 100,000 people passed through the airport on Sunday alone, and many have not seen their suitcases since.
Italy's Civil Aviation Authority claims that baggage handlers have been sabotaging outdated or obsolete equipment, causing huge delays.
Both arriving and departing passengers have been affected.
Piles of thousands of pieces of luggage have accumulated in various parts of the airport, and angry passengers have been demanding compensation for lost or delayed baggage.
After one MP dubbed the crisis a national disgrace, government ministers have called for an immediate inquiry into the chaos at one of Europe's busiest airports.
