A Dartmouth Avenue man remained in custody at the Erie County Holding Center Wednesday night, a day after he was arrested for allegedly lacerating a woman’s throat with a trowel during an argument in a car on Grider Street near East Ferry Street.

Robert L. Patton, 47, was arrested by Officers Thomas Herbert and John Sullivan shortly after the incident at 7:20 p.m. Tuesday. He was charged with second-degree assault and criminal possession of a weapon for allegedly cutting the woman’s neck and threatening to “cut deeper,” according to a police document. The woman sought medical attention on her own after Patton’s arrest.
