Norwegian police plan to question the former member of the far-right English Defence League (EDL) described by confessed killer Anders Behring Breivik as his "mentor".
Paul Ray will travel to Norway today where he will voluntarily submit himself to police investigating the twin attacks on July 22 that killed 77 people, a spokesperson said.
"(He) wants to explain himself to police and the police want to hear his explanations," said Unni Turid Groendal, Oslo police spokesperson.
"He is set to come to Norway tomorrow (Wednesday) and will be questioned by police the same day," she added.
Mr Ray is widely considered to be the unnamed "mentor" mentioned by Breivik in the 1,500-page manifesto he posted online shortly before carrying out his deadly attacks. Describing himself as a crusader at war against multiculturalism and Islam, Breivik, 32, explained in the document that he had had "a relatively close relationship" with an Englishman he gave the pseudonym "Richard", "who became my mentor."
Mr Ray, who heads the "Knights Templar" movement and runs a "Richard the Lionhearted" blog, has said he recognised himself in the Norwegian right wing extremist's description and worried that he was Breivik's inspiration.
Mr Ray has called the attacks "pure evil", and had told Norwegian media he planned to come to the Scandinavian country to clear his name, saying he did not know the Norwegian killer.
