       Footage posted on social media showed demonstrators outside the doors of the building in White City, which was the BBC's former headquarters.

       Several police officers were seen standing outside and trying to guard the entrance to the building.

       "There have been no arrests but officers are in attendance and will continue to monitor the situation."
