I think my friend is being sexualy abused.

So last week I invited two of my friends to my house. One of them is a 15 year old girl who we can call "Lizy". So Lizy, me and my other friend were enjoying and watching some anime and movies on Netflix. Lizy got a call from someone and she had to go somewhere else to talk. She went for a good 15 minutes or something so I got worried and went to check on her. She was outside the door and I could hear her crying. When I came outside she quickly wiped her tears and started pretending to play a game on her phone. I was really... I don't know.. confused..? But I didn't bring up the subject. She just gave an excuse and left saying that she had some homework to do. After the weekend finished, it was time to go to school. I was on my way from home to school as usual when I saw her right across the street and well, as all normal friends, I greeted her. But when I saw her face, I seriously couldn't recognise her. She had dull eyes, as if she had been crying the whole week, her skin was really pale and she was skinnier than ever. We met up with our other friend and headed to school. At class, Lizy sits right next to me, I saw some scars or some type of line on her wrists. Almost as if they had been tied by a rope. I added 2 and 2 and figured this had something to do with the call. I finally questioned her about it at the end of the day. She said it was nothing and she was just sick and just went home. So in the evening I went over to her house to see if she really was sick. I heard screaming and the voice was clearly of lizy's. I knocked hard on the door, and Lizy's screams stopped abruptly. Her dad opened the door and gave me a "You Disrupted Something" stare. I asked where Lizy was and he said that she was sick and wanted no visitors. I confronted him about the screaming and he just said "Oh it was just a horror movie playing." I knew that he wasn't gonna budge so I just walked away. Lizy has not come to school in 3 days. I'm worried about her. I tried calling the cops but the won't believe me. Of course they wouldn't since I am a kid and he's a "grown-up". I just want to help her somehow. I know she's in trouble. I doing everything I can for someone to help me. I know this sounds like a stupid story but I'm serious!... Please believe me. And please let me know any way that I may be able to help her!

Before I offer up anything else, can I ask if you first have talked to Lizy yourself about this, including what kind of help she wants?
