Tammy Nguyen attended an A$AP Mob concert at the Fonda Theater in Hollywood in 2013, and claims that she was seriously injured at the show during a crowd surfing incident. 

The woman says there was lots of crowd surfing going down at the concert, and at one point A$AP Ferg jumped in the audience and allegedly hit her. Nguyen says she tried to hightail her way out of the show after being injured, but security was useless in helping her get out of the jam-packed venue. 

She is now suing both A$AP Mob and Ferg for unspecified damages.
