Three off-duty FDNY firefighters were arrested after allegedly beating a man up following the Mets home opener at Citi Field yesterday. Police say the fight happened around 8:30 p.m. at McFadden's Restaurant and Saloon on 126th Street and 37th Avenue in Flushing, near Citi Field. Firefighter Anthony Cardazone, 33, allegedly put the victim in a headlock while firefighters John Martin, 33, and Michael Profeta, 34, pummeled him.

It's unclear what prompted the fight. The victim, who has not been named, sustained cuts to his lip, bruises and swelling. He fled the bar after the alleged assault and notified a police officer working crowd control near the stadium.

Police say that when they arrived at the bar, Cardazone was "non-compliant, combative and refused to be rear cuffed." Cardazone, who was featured with his shirt off in a 2010 FDNY charity calendar, was charged with resisting arrest, assault, and disorderly conduct.

"His behavior was tumultuous," a police source told the NY Post regarding Cardazone.

Profeta and Martin were both charged with assault and disorderly conduct. The victim was treated at New York Presbyterian Hospital/Queens. The Mets beat the Phillies 7-2.
