Police have been instructed to arrest WikiLeaks founder Julian Assange "under all circumstances" should he leave Ecuador's London embassy, including if he was granted diplomatic immunity by the South American country or came out in a diplomatic bag.

The instructions for the tactics to bring in Mr Assange, including the possibilities of potential distractions, were captured on a police clipboard by a photographer.

Sweden wants to extradite him to face questioning over rape and sexual assault allegations.
