International soccer matches have a reputation for occasionally rowdy fans, but on Sunday Police in Turkey were dealing with a fan uprising not related to the outcome of a game but to a new e-ticketing system.
Fans of the Fenerbahce, Besiktas and Galatasaray soccer clubs took to the streets to protest a new e-ticketing system called Passolig that allows the operator of the system to view the ticket holder's private data, including their national identity data and banking information.
Police used tear gas and water cannons in an attempt to disperse hundreds of protesters on Istiklal Avenue in Istanbul, according to a report in the Hurriyet Daily News.
On the Passolig website the company details the reasoning behind the move to the e-ticketing system, citing "Law no 6222," the Law on the Prevention of Violence and Disorder in Sports.
