British authorities arrested WikiLeaks founder Julian Assange in London on Thursday, charging him with breaching bail conditions and exposing him to extradition to the United States where he faces a charge of computer hacking conspiracy.

Assange had spent over six years holed up in the Ecuadorian Embassy in London avoiding such extradition, as U.S. authorities have long sought to prosecute him for his role in WikiLeaks obtaining and releasing classified military information in 2010.

Although the ethics and legality of WikiLeaks operations and its motives are contested, the organization has through the years revealed undeniably newsworthy information that authorities sought to keep from the public. These are some of the biggest stories that came from WikiLeaks.
