RADICAL preacher Anjem Choudary is understood to be one of nine men arrested today as part of an investigation into Islamist terrorism.
The men, who were all seized in London, were arrested on suspicion of being members of, or supporting, a banned organisation, the Metropolitan Police said.
Al-Muhajiroun is understood to be the banned organisation in question, sources told the Press Association.
Counter-terrorism police are searching 18 addresses across London, and one in Stoke-on-Trent.
The men, who are aged between 22 and 51, were arrested as “part of an ongoing investigation into Islamist-related terrorism and are not in response to any immediate public safety risk”, Scotland Yard said.
