“Julian Assange is the publisher of the truth,” he wrote.
According to him, Assange did a great job for the sake of humanity, despite the inhuman attitude.
"This case is crucial to preserving our right to information and our true freedom against oppression - and now tyranny - from the US and the UK," said Stone.
An AFP source said earlier that Assange is being held in a high-security prison in Belmarsh in London.
On April 11, Assange was detained on the territory of the Ecuadorian Embassy in London in connection with a request for extradition by the United States. The court decided to leave him under arrest.
