Replying to Sketchy thing at dorm

So I was with this one girl and she was feeling pretty sick and had a fever, so I went to my dorm to grab some ibuprofen and then biked back over there to give it to her and she had meet her at the back door because the front is locked. So I gave it to her then this alarm went off and I biked away... she said it turned off but when I got back to my dorm it looked like the cops showed up. Am I in trouble? I don't want to deal with the po-po its my first week of college!
