All my years going to the match I have never seen this kind of thing on a match day.
Sounds like a made up story to me.
I've seen people bang on cars when they are trying to barge their way through a crowd, but a swarm of fans banging on a car with a young lass in it trying to topple it over....... ner I call bull shit.
Not a police officer in site then I take it.
Sounds like he needs to go to r/thathappened imo.
