An Oak Forest man was arrested Friday in connection with the sexual assault of a woman in Park Forest last week.
Marc Greska, 34, faces a felony charge of aggravated battery.
Police say a woman walking near Shabbona Park was approached by a naked man wearing only boots and a skull cap. The man grabbed her waist from behind and thrust his pelvic area toward her.
Greska is also charged with a misdemeanor count of disorderly conduct after police say he was seen in the same area on Wednesday wearing only boots and a hat, although he's not accused of confronting anyone in that incident.
Police are still looking for suspects in two other assaults in the area during the same week, although Greska has been ruled out in those incidents.

In the first incident, a teen walking through Winnebago Park was robbed at knife point, and the robber also fondled her breasts through her shirt.
Another teen girl was confronted by a man at Westgate Street and Westwood Drive, and began fondling her body over her clothing. Police say no weapon was involved in that incident.
Anyone who may have witnessed any of the incidents or has information is asked to call the Park Forest Police Investigations Division at 708-748-1309.
