How do I put my grandpa in jail??

Hello everyone, im a 16 yo girl and i think i definitely need help right now

Every holidays I go to my grandma’s house (and now I’m here for two months), the issue is that I have uh a quite alcoholic and unintelligent grandfather, and I mean it, he doesn’t like me because I don’t submit to him… as in letting myself getting insulted, not doing everything for him (he’s quite the sexist guy😬😮‍💨) and we’ll, it’s going horribly right now 💔 I haven’t been speaking to him for a month now (it’s already the second time this year erm) because he screamed at me for some stupid light I left on by accident, and ofc I got insulted of all names, he said he’d throw me out on the street too. It’s not the first time it happens, last time, I was also threatened to get hit, literally… So I started audio recording when I felt like it was going to go bad, I only have two audios right now tho… The thing is, today, I was chilling on the sofa, and I kept the remote because I KNEW he’d come and turn on the tv (he’s like SO jealous of me because my grandma loves me🤦‍♀️ and keeps trying to do things to piss me off, but I ragebait him better😛). So he came at some point, and searched for the remote (which was almost under me) and when he saw it, guys Im telling y’all, he reached for it, I pushed his hand away, once, twice, THRICE😪 He kept going at it so I started pushing him away more harshly, I’ll admit it, but I hadn’t done anything till now I swear😢 And he KEPT GOING. So I started to scream for him to stop touching me (I HATE getting touched by adults I don’t like), and my grandma came of course RIGHT as he lifted his fist, ON GOD he was going to punch me😭😭 It kept going for a minute and he kept and kept and keptttt going at it, he wouldn’t leave me alone omg so I tried to kick him away (for reference Im 170cm and 50kg, he’s taller and probably three times my weight), but I gave up and threw the remote on the ground because I was SO pissed, then I started audio recording… he kept insulting me again and I told him to go get mentally checked 🙄🙄 because he’s insane I swear…

The thing is, he’s only like that with me because I’m the only one to not bend to his rules or mood swings, or whatever… so I’m scared to go tell the police or something, I quite want to do the remote thing again tomorrow and this time record it all, and not give up, I want a concrete proof for the police, should I do it?? Or what should I do please I’m desperate at this point and very scared
