On February 12, 2015, six members of the hacker group Fallaga Team were arrested by Tunisian authorities over their part in #OpFrance - a coordinated cyber-attack on French websites in the wake of the Charlie Hebdo shooting in Paris. According to the Tunisian Pirate Party, the six were "kidnapped" on orders from NATO and the U.S. ambassador to Tunisia.
In response, Fallaga Team threatened retaliation and said they had secret files that they would publish unless the members were freed.
