The 39 year-old told journalists at the Frontline Club last night that US government insiders had informed him about discussions to charge him as a co-conspirator to espionage.
The discussions were later dropped.
Mr Assange says despite this he still fears he is at risk of being forcefully detained by the US government as a material witness in the prosecution of US intelligence analyst Bradley Manning.
Mr Manning, 22, was arrested in Baghdad in May and charged earlier this month with multiple counts of mishandling and leaking classified data, after a computer hacker turned him in.
If it is true that the administration or anybody in our government told this man that, I hope they are shot dead. Fucking traitors.
