I [M21] was at my friends [F20] house for a party. We were drinking, people were leaving until it was just me and her left. We were talking on the couch, started making food, and then she invited some friends she hasn’t seen in a while over. Three guys came over and as soon as they got there, one of the guys kept telling me how I need to “get out and go home because you know what’s going down.” I never met these guys before and thought they were just playing and being drunk until the big friend decked me and I went flying into the wall. The friend in the back started screaming what are you doing?? On the floor, clearly not in a good position to start a fight, I went to leave and the big friend pushed me out the door and I again went flying into the wall outside the apartment. Then went to my nearby friends place, and called the cops from my friends phone. I then went back because my shirt, wallet, keys, and phone were still at her place. Outside her door my shirts thrown in the middle of the hallway. I slowly open the door, and was told to get lost because “stuff was going down.” As I was walking down the hallway I hear, “Hey pussy want your stuff back?”. So I go back and they throw my stuff on the ground. I thought I could hear my friend crying/in distress in the room but I could also be mistaken. So then I called the cops, told them I thought there was a rape occurring at that address. They show up to knock on the door and there’s no answer. 

It’s the morning after, I for whatever reason couldn’t get much sleep last night. Woke up to texts from a different friend told me that it was wrong of me to do that because my friend was underage drinking, that guy was her ex-boyfriend and everything was fine. 

Haven’t heard from the friend despite me texting her. AITA for calling the cops? How should I’ve handled the situation, I thought about taking the guys on (wasn’t sober myself) but it was 3 on 1 and I was in no state to fight given how drunk I was. I’m in PA btw.
