The Girl With the Pink Tattoo

You head the way you came into the alley. The man runs after you and ends up catching you. He drags you back into the alley and into the apartment. He lets you go and locks the door. When he walks back to you he begins to kick you and punch you. That's when your eyes go weak and you suddenly fall asleep. Two hours later you wake up and the man is nowhere in sight.

What do you do now?
