Minors and protecting yourself

[Anonymous]

So picture this....

I got attacked a 17 year old male (My partners son). 6 foot tall and quite An athletic lad.
He punched me and tried taking me to the floor.
I defended myself. I did NOT strike him and there is literally zero marks or bruises on the lad. All I did was restrain him and hold him in a head lock until he seemed to calm down and then I let go and told him to leave.

His reason for attacking me are still unknown to me and also the police.
Who were called by me.

What I’m confused about though....I was attacked in my home and I was the one arrested for defending myself with what I consider reasonable force.

I now have social services crawling up my backside because I have 3 children of my own at home.

Police dropped the charges after interview and I walked out without charge.

Wtf is going on in this country (UK)

When I can’t defend myself without facing charges you know there is something wrong!!

My children were right next to me in the same room and saw the whole thing. This is why social services are involved. 

I actually asked the police and social services what I was supposed to do it this situation.
Both authorities told me they cannot give me advice on this.

So basically in the UK....Kids and Teens are running the land !!

Anyone else had something like this?

What were social services like?? I have never had them involved with my children before.
