In the UK can the police charge someone?

Question

who threatens physical violence against you? what kind of action can be taken?

Answer 1

I can't answer for the UK but in Ireland there is a section under the Non Fatal Offences Against the Person Act 1997  

Section 5

A person who, without lawful excuse, makes to another a threat, by any means intending the other to believe it will be carried out, to kill or cause serious harm to that other or a third person shall be guilty of an offence.



(2) A person guilty of an offence under this section shall be liable—



( a ) on summary conviction to a fine not exceeding £1,500 or to imprisonment for a term not exceeding 12 months or to both, or



( b ) on conviction on indictment to a fine or to imprisonment for a term not exceeding 10 years or to both.

So, as you can see, yes there is a possibility that the UK has something similar.
