Awesome. You can understand somebody flipping-their-sh*t over getting cut-up or whatever, but (multiple) citizens arrests combined with threats to kill them is next-level bonkers. Feel a bit sorry for him actually.
I think he might find himself in court…. threatening to kill somebody is an offence – I had a similar case while I was on jury duty. One chav issued a really round-about threat to his girlfriend – we all got a lecture from the judge on how it was really serious.
From the CPS:
Threats can be calculated and premeditated, or said in the heat of the moment. The defendant does not have to have the intention to kill but there has to be an intent that the person to whom the threat has been issued would fear it would be carried out. This can be a difficult offence to prove, and it should be reserved for the more serious cases. Where it is doubtful whether the threat carried the necessary intent a charge under Section 4 Public Order Act 1986 may be appropriate.
