Fearing that his freedom may be short-lived, WikiLeaks founder Julian Assange has said that the U.S. was preparing to indict him on espionage charges and it was likely that he may be extradited. Mr. Assange, who had an emotional reunion with his mother at the 600-acre Suffolk estate where he is currently under house arrest after being released on bail, told newsmen: The U.S. is preparing to indict me on espionage charges. I am afraid my freedom may be short-lived. He said an illegal investigation is being carried out against him, the Daily Mail reported. A spokeswoman for the U.S. Department of Justice would confirm only that there is an ongoing investigation into the WikiLeaks matter.
