They ask you to come to station to help with enquiry if you say no they arrest you 9 times out of 10 lol
Regardless of circumstances and this scumbag who died the fact is there a dead body it has to be investigated.
It's the UK not dodge city we live.
He's not been charged and if the story is right it was one stab blow to the chest after a scuffle and the c**t died in the street. He be fine the CPS will not pursue it if these facts are correct
