Called the police on my dad for harassment and they still haven’t arrested him

Help

I’m 18F and my dad is 49M.

This week I’ve reported him for malicious communication as he has been threatening to come and hurt me(and “kill me” more than several times. I went to the police 4 times, gave 3 statements, with over 20+ screenshots of evidence of his behaviour towards me, overtime escalating to a harassment case. Despite never actively hurting me, I’m worried for my life.

They have “tried” to find him, and I have given an address that he is at , and even though they said they will go ahead and arrest him - they haven’t. At this point he has contacted a friend of mine, threatening to come and hurt them as he suspects that I’m in a relationship with them - which is not the case. They have blocked him but he knows of the region they live but nothing more. FYI- the reason this started was bc he wanted to see me this week and I said “I don’t know” as we haven’t seen each other a 5 months prior due to this behaviour of his. He would throw racial slurs at me and call me horrible names unsolicited for days on end and just go quiet.

I told this to the police but they still haven’t done anything.

I’m supposed to go out with said friend tomorrow and I feel sick to my stomach that this is all going on and he is still isn’t in custody. He has made threats against me and my family.

I went to the police station to ask about my case and they were unwilling to go into the database to see any updates.

He blocked off my service so I had to buy a new phone with a new SIM card. He is defaming(if that’s the word) on his instagram story about how I don’t want to talk to him anymore - WHEN HE GAVE ME NO CHOICE BUT TO CHANGE MY NUMBER. He’s following my friends accounts on instagram, messaging me on insta about them ,calling them horrible names (I’ve restricted him on there so I can use anything he says as evidence but also as a safety precaution).

I’m scared for my life. He has thrown threats and hasn’t done anything, yet he is now contacting this friend of mine.

I haven’t spoken to him at all for a couple of days since I had to report him.

Is there any advice to navigate this situation? Emotionally mostly

Any tips on how to calm down my mind and not jump to conclusions. I feel alone , my mother has passed and my family aren’t interested so much in this).
