Off-duty NYPD officer on her way to work is attacked by a stranger

An off-duty NYPD officer on her way to work was attacked by a stranger outside a Dunkin Donuts in Harlem on Wednesday morning, cops said.

The 43-year-old sergeant was holding a tea and walked out of the store at West 125th Street and Lenox Avenue around 6:45 a.m. when a babbling man attacked, sources said.

The sergeant was in plain clothes when the crazed man — who was speaking incoherently to himself — punched her and knocked her to the ground, sources said.

Before she could react, he socked her a second time and then took off, cops said.

The suspect is believed to be in his 30s approximately 6 feet tall and 200 pounds. He was last seen wearing a blue jacket, blue jeans, and a baseball hat with orange, blue and white coloring, cops said.

The sergeant was rushed to St. Luke’s, where she was treated for a contusion to the back of her head and received five stitches for a gash under her left eye, cops said.

Cops said there was no way for the man to have known she was an NYPD sergeant.
