Something's suspicious here. Your flatmate told you that he didn't hold a party while you were away, but you feel something fishy about his statement. As soon as you arrived home, you had this feeling. Things are in different position than they were when you left. I'm sure they broke something or did something bad.

Maybe they punched in a wall? Let's go!
