A Bronx man has been indicted on an attempted murder charge for allegedly using a nail-studded plank to beat his ex-girlfriend — who lost several teeth and her vision in one eye during the horrific attack, officials said.

Grand jurors returned an indictment against James Fitzgerald, 53, for the brutal assault on his estranged girlfriend on a Jamaica, Queens, street in May, the Queens District Attorney’s Office said.

In the early evening of May 16, Fitzgerald allegedly attacked the 35-year-old, who was prone on the ground in front of a fish market, as witnesses begged him to stop, officials said.

At one point he walked away — but allegedly returned with the nail-spiked plank and slammed it into her face so many times that she lost consciousness and several of her teeth broke off and flew onto the sidewalk, authorities say.

The woman, who is now permanently disfigured, suffered a crushed orbital bone and blindness in her right eye — despite three surgeries, according to prosecutors.

Fitzgerald is also charged in connection with a prior April 17 assault on the victim, in which he allegedly pummeled her in the head and face.

He’s being held without bail and faces up to 25 years in prison on a six-count indictment, including charges of attempted murder, assault and weapons possession.
