Section 20 assault; Thats GBH....
Here's me hoping he just 'bumped' into the 87 year old woman by accident and she was knocked over.
Sounds plausible to me with a fractured hip and cuts to her arm.

He's guilty of badly impersonating a referee and getting away with it for a long time now.

there's a bit more info here

which may shed a bit more light....... maybe

Hmm

If he needs a legal team,I'm sure Steven Gerrard could point him in the right direction.
