Revellers throw punches, hurl chairs and brawl in vicious fight at New Year concert party

This is the moment a violent melee broke out between revellers at a popular New Year concert.



Shocking mobile phone footage captures party-goers wrestle on the floor, throw punches and use chairs as weapons.



Disappointed organisers say the Hmong New Year concert in Fresno, California - held five days before the new year - was marred by violence on Wednesday and have slammed the behaviour in the footage as "unacceptable".



In the short clip, yobs grapple on the floor before others smash chairs against other revellers.



Security staff try to intervene but the shocking melee quickly escalates into a violent brawl.
