That doesn't sound like a creeper at all. Your friend didn't think he was into her and that's why she hung out with him, but now that she knows she doesn't want to anymore... are you missing something from the story? Not wanting to be around someone because they're attracted to you is not at all the same as being stalked by a creepy person...
Just tell him the truth and don't dick around. You haven't even told him to not hang around with you guys anymore, you haven't tried anything to get rid off him, so why ask for advice? Trying to find "clever" ways to get away from someone without telling them, that's just rude.
