A creep sprayed an unknown substance in the face of a man and his 2-year-old daughter on a Brooklyn street, cops said Tuesday.

Jesus Centeno, 42 came up behind the 25-year-old father as he carried his child down Broadway near Thornton Street in Williamsburg around 8:40 a.m. Oct. 6 and sprayed their faces before fleeing, cops said.

Police said the man knew Centeno, and the attack was likely the result of a dispute over narcotics sales.

Both the father and little girl were taken to Woodhull Hospital, where they were treated and released.
