An intruder dressed as Freddy Krueger is still at large after he opened fire on a Halloween party and shot five people.

Two men showed up to the costume party in San Antonio, Texas, early Sunday and began fighting with guests.

The man dressed as the Nightmare on Elm Street fictional serial killer then began shooting.

Party-goers who were wounded in the shooting were all treated and released from hospitals.

Police say alcohol is thought to have played a role in the incident but it is unclear as yet what prompted the fight.

Both men fled the party and have not yet been caught by police.
