Crash in Piccadilly Gardens

Bloody hell.
There was terrible violence in Piccadilly Gardens.
As you know, battle was suddenly happened because of technical fault in a big screen which a lot of football fan looked at.

As well as this, huge trash were left everywhere, even in Oxford road which is located not near to Piccadilly Gardens.

I heard several siren of ambulance car in very early morning, because I live near to A&E department at Manchester Royal Infirmary.
I am afraid that someone should be injured there.

One of problems was a technical fault, but I am wonder why the fault was occurred in the most important day for both many rangers fans and Manchester city and why were not prepared spare screens in such case.

As long as I know, there is violence in every football match.
I prefer completely careful game and atmosphere.
