@hottyboi,
I think her Father is telling you to back away, you are obsessed with his daughter but she is not with you. Or, is it that she told him of the situation and he threatened you to keep you away from her, more info?
Then there is the fact that you tried to seek attention from her, lying you know you only do that part, " I'm injured, I'm an officer" etc, if she is not into you, she is not into you.
Leave her alone is my suggestion, just because "you" may like someone doesn't mean they do back.
