The U.S. charged WikiLeaks founder Julian Assange with computer hacking conspiracy, according to the Justice Department.
He was arrested Thursday at the Ecuadorian Embassy in London after Ecuador revoked his asylum.
Ecuadorian President Lenín Moreno said in a video the country "has reached its limit on the behavior of Mr. Assange" and listed specific incidents leading up to the decision.
Assange had been granted asylum by Ecuador and was living in its embassy since 2012. He was avoiding extradition to Sweden for sexual assault allegations, which were eventually dropped.
Now, with the asylum withdrawn, London police detained him on a U.S. extradition warrant.
The charge stems from when WikiLeaks published thousands of classified documents provided by Chelsea Manning back in 2010. At the time, Manning was an intelligence analyst in the U.S. Army.
If convicted, Assange faces a maximum penalty of five years in prison.
