Jennifer Lawrence ran away from a signing session in New York City after fans knocked down a barricade in front of her.

The Hunger Games star stopped to greet devotees and sign autographs outside the Ed Sullivan Theater in New York City following her appearance on The Late Show with David Letterman on Wednesday night (12Nov14).

However, her time outside was cut short after a barrier keeping fans contained fell down, prompting Lawrence's security guards to grab the actress.

Video footage posted online shows the Oscar winner running to the safety of a car with her bodyguards by her side.
