The FBI is asking for the community’s help in identifying a suspect wanted for a possible hate crime after the man allegedly struck a victim in the head at a CTA Red Line station on the North Side last month.

According to the FBI, an unknown suspect followed a male victim into the station at around 1:18 p.m. on Aug. 15. The suspect then struck the victim in the head from behind, causing him to fall. The suspect then said the victim deserved the assault and used an ethnic slur against both the victim and his partner, the FBI said.

The suspect is described as a Black male with a medium build and thin goatee facial hair. In the published photos, he can be seen wearing a diamond stud earring in his right ear, a silver watch on his left arm, a metallic bracelet on his right arm, a gold-colored chain around his neck and a Chicago White Sox baseball hat.

A three-second video also published Tuesday shows the suspect walking down a flight of stairs at the Red Line station.
