MI5 stopped Scotland Yard taking Anjem Choudary down, sources claim

The security services repeatedly prevented Scotland Yard from pursuing criminal investigations against hate preacher Anjem Choudary, it has been claimed.

Met counter-terror officers often felt they enough evidence to build a case against the radicalising cleric, only to be told to hang fire by MI5, because he was crucial to one of their on-going investigations, a source has claimed.

He did seem to have a long leash, my suspicion remains that he was working for the security services.
