CHICAGO -- The sexual assault of a woman on the South Side is getting new focus after police asked for the public's help in the case, releasing a new sketch of the suspect.

Chicago police say on a 28-year-old woman was walking in the Chatham neighborhood around 4:30 a.m. on April 24 when a man approached her from behind, forced her into an alley at knifepoint, and then sexually assaulted and robbed her.

Neighbors in the area near 79th St. and Wabash say that type of crime is unusual there.

And while it happened more than a month ago, Chicago police say they're just now sending a community alert after initial leads dried up, hoping the public can help identify the man.

"If he's still out there he could do it to another female so hopefully they catch him," said neighbor Jessica Young.

People who live in the area say they do not recognize the man in the sketch from the neighborhood.

Police say the suspect is a black male 20-25 years old, 5'7" to 5'9" and 130 pounds. He was wearing dark clothing at the time.
