Cops are looking for a man who confronted a random woman on the street in Brooklyn and socked her in the head, cops said.

The man went up to the 27-year-old woman near Crown Street and Nostrand Avenue in Crown Heights at about 12:10 p.m. on March 9 and slugged her, according to video footage released by cops Wednesday.

The suspect, who was wearing a blue Yale sweatshirt, ran down Nostrand Avenue, police said.

The victim drove herself to Kingsbrook Jewish Medical Center and was released shortly after.
