A spokesman for London's Metropolitan Police said it had arrested 20 people "for further investigation around being suspected of being a member of a proscribed group." "There were two further arrests, one for obstruction, one for violent disorder. They are currently in custody," the spokesman told AFP, confirming that the arrests were outside the US embassy. The Press Association news agency said the demonstration was in protest against attacks by US drones targeting militants in Pakistan and that a number of demonstrators remained at the scene. Interior minister Theresa May said at the time that the organisation had already been proscribed under a number of names, including Al Ghurabaa and Islam4UK.
