There is an explosion of noise on the tape at this moment, and you can hear the cage being rattled frantically with accompanying screams of rage (Jimmy again?).  Camera flash lights are going off every second or so, and the light bouncing off the cage mesh messes up the video.  But, the nameless cameraman presses forward and pushes the lens of his camera through the mesh, so that for a few seconds we get an unobstructed view of Sancha face-sitting her victim.  A magic scene!

Next thing we see is the camera shot moving rapidly upwards to show the ceiling, then we are treated to a scramble of heads, legs, arms and finally a close-up of the floor.  All this is accompanied by a cacophony of shouts and screams.  Then the screen goes black.

I understand that at about that time the police arrived in force presumably called by Helen's boyfriend (the dreaded Jimmy again?).  Sancha was arrested and kept in the local police station overnight.  The next day she was released and left the Island without any charges being made against her.
