The NYPD is looking into a brawl caught on video of a group of men dressed in Santa suits.
Police say the men had dispersed by the time officers responded to the scene near Union Square on Saturday evening.
The video was posted on YouTube.
The NYPD says no one filed a complaint of an assault on Third Avenue between 16th and 17th Streets.
Police say it wasn't clear if the group had been participating in the annual pub crawl known as SantaCon.
SantaCon started Saturday morning in Tompkins Square Park in the East Village. Thousands of red-suited revelers then spread out through the city's bars and snowy streets.
The event has been criticized by some for being too rowdy.
