This guy doesn't sound like a friend, infact he sounds like a fucking twat.

Why would he make up a lie that is so easy to prove wrong? What with your witnesses etc...He's just gonna come out looking like the biggest fool of all. You never fully come back to a group of friends after getting caught out trying to manipulate one of them like that.

If I were in your shoes, I'd demand an explanation - If he refuses, I seriously would consider a swift and clean jab to the face. Sounds as though its one of the few times when someone truly deserves a physical stir-up to let them know they've gone to far.
