Two men attacked a woman with pepper spray and then snatched her backpack on a Hoboken street Wednesday night, city authorities said.

The robbery occurred at 9:06 p.m. on Bloomfield Street between 12th and 13th streets, Lt. Danilo Cabrera said.

The victim was walking alone when the men sprayed her face with a chemical irritant and forcefully grabbed the backpack and fled south.

Cabrera said one of the assailants, who were described as young adults, was wearing a black down winter jacket, black pants with a white stripe down the side and white sneakers. The second man was wearing a black hooded sweatshirt, black winter jacket, black pants and black sneakers.
