A senior volunteer for Wikileaks in the US has been detained, questioned and had his phones seized when he returned to the country from Europe, as the FBI steps up its investigation into the leak of thousands of Afghanistan war secrets to the whistleblower website.
Jacob Appelbaum, who has stood in for Wikileaks founder Julian Assange since he was advised not to travel to the US, spent three hours at a New York airport while customs officers photocopied receipts and searched his laptop, and he was again approached and questioned by FBI officers at a computer hackers conference in Las Vegas.
