Unhinged woman storms NYC restaurant, whacks diner with glass bottle before socking four others in random attack

An unhinged woman allegedly stormed into a Brooklyn restaurant and whacked a diner with a glass bottle before socking four others in a random attack Saturday afternoon, authorities said.

Hilda Grullon, 44, allegedly launched her crazed attack when she busted into the Burrito Bar & Kitchen at 307 Flatbush Avenue in Prospect Heights around at 3:28 p.m. and bludgeoned a 63-year-old man with a glass bottle, according to the NYPD.

The deranged suspect then barreled out of the Tex-Mex eatery and ambushed four more people — including a 52-year-old man and two women, 20 and 53, whom she clobbered in the face.

The final victim, a 36-year-old woman, was pummeled in the head with a cell phone, police said.

The first victim was transported to New York-Presbyterian Hospital in Brooklyn, while the remaining refused medical attention at the scene.

Grullon, of Brooklyn, was taken into custody following the unprovoked assaults.

She was charged with criminal possession of a weapon, three counts of assault, two counts of harassment, and endangering the welfare of a child.
