Can I kick out my 17 year old son

[rainbowglitter23]

so my 17 year old sons behaviour is awful, he’s rude, abusive, swearing all the time, threatens everyone
it’s just me him my 15 year old DS and 20 year old DD at home
my 17 yo was arrested for assaulting my 15 yo and also had two cases of abh against him from my daughter yet police and social services have done nothing
my youngest has been sleeping on the sofa for months as they used to share a room, my daughter can’t really move out as she’s signed off sick due to her mental health, she could potentially go on council list but i am also her carer as she has autism and not entirely sure she’d be okay living alone
what can i do? ik by law parents are responsible until they are 18 but im also responsible for the safety of my 15 yo, my daughter and myself

can he go and live with his dad?

Is Dad in the picture? Have you spoken to SS about the risk to esp the 15 as she's a child?

Go down the the local SS department, ask to speak to duty, tell them they need to work with you because the 17yo isn't safe with the 15yo. Don't leave until they have a solution. Ask for anything they say in writing.

Can he go to his dad's?

Dad isn’t in the picture so that’s not an option
Was supposed to get help from the police think they were the familye or the community youth worker or something but heard nothing from them expect some letters not saying much

Factually you can stop providing a home to any child.

If possible it would be better to get help as doing that is a drastic last step. However you have violence in your home so you are in an urgent situation.

You need to speak to everyone you can to try to get help. Go via the school to explain the risk to your 15yo and go to social services yourself. Chase the police.

The sleeping arrangements - it isn't fair that the 15yo victim is on the sofa. Is there scope for you and your DD to share short term to give the 15yo a room? Put a lock on his door.

Does your 17 year old know it has come to this? Surely if it’s a choice between stop the aggression or move out they may want help controlling themselves? Why are they so angry?

He can apply to the local housing department as a homeless teen. It probably wouldn't be social services arranging accommodation for him under those circumstances but they would get involved to assess his needs. If you make him homeless they should provide him with somewhere to stay.
how did it get this bad? Is there anything you can identify that led to this breakdown?

You can make phone calls in the morning to try to get help. Phone:
Police (to chase up)
Youth Offending Team (to see if police reported)
Social Services (to report it and explain you feel you can't safely house)
School (to explain your 15yo's situation and ask them to try to escalate referrals)

Would your 17yo go to the GP to see if there is any help that can be offered for their own MH which would help calm the situation?

Thank you, school aware but i’ll chase them and see if they can flag it
unfortunately our house is technically three bed but more one room, one box room (my room) and my daughters is even smaller it basically has her bed and some storage and that’s all that fits - i’ve tried getting the 17yo to sleep on the sofa but that just ends in shouting throwing stuff etc, he’s trashed my daughters room in the past and he’s not small by any means so like if he wanted to hurt someone or break something he could so i’m not sure how i can ‘force’ him to do anything like any consequence he doesn’t care and acts like it’s the whole world against him
