Update 17 April 2023: he has been caught.
Thanks to Simon Anderson for this video, which clearly shows Granny’s just standing there.
She notices the feral pack has smashed down the barrier, and appears to be trying to escape or tell off the meth-looking woman who is pulling out the stakes on the inner barrier. Then the TRA thug identifies Granny, goes through the barrier straight to her, pushes her to the ground, then smashes her face in when she got up.
The action takes place in the center of the frame.
Here are some photos of the basher, if you recognise him, please let the Police know.
(I do wonder what he’s checking on his phone.)
