Falcani was detained on April 4, when he was going to take part in one of the events at Spain's University of Comillas.

In 2015, the Federal Court of Switzerland sentenced Falcani in absentia for five years in prison. The court found the former employee guilty on charges of economic espionage. Between 2006 and 2008, Falcani gathered information on 24,000 people who had accounts in Swiss HSBC subsidiaries. Data gathered by Falciani reportedly contained mainly account details of individuals using Swiss banks to avoid taxes.

In 2009 Falcani arrived in France and leaked the data to the French authorities, who then passed it to the United States, as well as Spain, Italy, Greece and other EU countries, which led to a number of lawsuits.
