Alright Sutherland!

NEW YORK (WPIX) -- Sources tell PIX News that a complaint was filed against the actor Tuesday after he headbutted a man while attending an after party for the Metropolitan Art Institute's Costume Gala Monday night.

The alleged victim, who has been identified as fashion designer Jack McCollough, was seen nursing what appeared to be a broken nose when leaving the First Precinct in Lower Manhattan Tuesday night.

The incident reportedly happened around 2 a.m. outside a SoHo nightclub Monday. McCollough is claiming he suffered only a laceration to his nose when Sutherland attacked him following a heated argument.

According to reports, the scuffle between Sutherland and McCollough erupted after the designer pushed actress Brooke Shields.

The incident, which was witnessed by Kiefer, prompted the "24" actor to rush over and assist Shields - who happens to be a former co-star.

Sources tell PIX News, when Sutherland demanded McCollough apologize for the incident, he refused and immediately dismissed the actor. McCollough, who is one half of the fashion design duo Proenza Schouler, was seen shoving Sutherland who responded with a headbutt.

Kiefer, who is currently on probation for a 2007 DUI bust, has not responded to the allegations. Sources say he has not been questioned by New York City police as of Tuesday night.

As far as Shields' involvement, earlier reports claim she had nothing to do with the brawl between the Sutherland and McCollough. However, a source tells celebrity website TMZ that "Brooke was definitely involved."

PIX News has learned that New York City police want to talk to both Sutherland and Shields to get their account of the incident, as they further investigate the matter.
