Authorities reported that the first incident was reported last Friday at approximately 3 p.m.

In this incident, a woman was walking along Brookbank Road in Downers Grove when Koranteng allegedly exited his parked vehicle, approached her from behind, and then walked past her before grabbing her buttocks. During the encounter, he reportedly asked if she would have sex with him. Koranteng then fled the scene in a Toyota Corolla.

The next report was made from Hinsdale, occurring on the following Monday around 2:45 p.m.

The alleged victim was walking with a 6-month-old child on a path on 59th Street. When she briefly stopped, she allegedly felt Koranteng grab her buttocks from behind with both hands. When she turned around, Koranteng allegedly reached down and touched the victim’s genitals over her clothes. When the victim screamed for help, he fled the scene.

The third report came in from Darien on Friday around 10:15 p.m. A woman reported that Koranteng followed her into the lobby of her apartment building and grabbed her buttocks before leaving.

After authorities identified Koranteng as a suspect in these cases, officers witnessed another alleged assault while conducting surveillance on him.

It happened on Friday in the 7300-block of Fairmount Avenue in Downers Grove.

Koranteng allegedly got out of his vehicle and approached a woman who was with her grandchild. While the grandmother was bending over to pick the child up, Koranteng allegedly grabbed her buttocks from behind and tried to wrap his arms around her. When the woman pushed him away, Koranteng fled back to his vehicle, where officers arrested him.

A judge ordered Koranteng, of the 400-block of Ridgemoor Drive, detained ahead of his trial on Saturday morning. He is due back in court on Dec. 8.
