A milkman who wanted to overthrow the government because he believed it had been taken over by Jews, has been found guilty on three counts of possessing terror documents.
Nicky Davison, 19, of Annfield Plain, Co Durham, was the co-founder of Aryan Strike Force, an on-line extremist neo-Nazi group.
The jury at Newcastle Crown Court took 50 minutes to convict the teenager.
His father Ian Davison, 41, a disc jockey, earlier admitted six charges, including terrorism and producing a chemical weapon. He was discovered in possession of ricin, which can prove fatal.
