U.S. Tv host Jimmy Fallon escaped unharmed after he was reportedly caught up in a bar fight in New York City on Thursday night (10Apr14).

The Tonight Show presenter is said to have joined a group of friends and colleagues for a post-work outing at Manhattan bar Niagara when a brawl broke out among other patrons.

Fallon and his group were caught up in the chaos, but managed to escape without injury, according to the New York Post.

A source tells the newspaper's Page Six gossip column, "There was a kerfuffle, a dust-up amongst other patrons. Jimmy was caught up in it, but was not hurt and turned around and left. It was not caused by him and he was in and out in five minutes."
