Detectives say the man struck a 25-year-old woman on the head as she walked along 7th Avenue two weeks ago.
It appears the attack was unprovoked.
The woman suffered a gash on her head along with some bruising.
The suspect is described as a man with a medium build. He was last seen wearing a black jacket, gray pants, a blue knit hat, and gray sneakers.
