Police question three men suspected in attack.
Three persons of interest interviewed in connection with a New Year's Eve sexual assault were released late Sunday with no charges filed.
The men were taken into custody Sunday after an 18-year-old Highland Park woman was beaten and assaulted Saturday night in the Logan Square neighborhood, according to Chicago Police.
The woman was turned away from a concert at the Congress Theater because she didn't have an ID, according to the Chicago Sun-Times. She reportedly was seen walking with six young men shortly afterward across the street.
Police confirmed the woman was found naked and bleeding at about 9:30 p.m. on the sidewalk in the 2100 block of North Rockwell Avenue, around the corner from the theater.
A Congress Theater employee told the Sun-Times three of the men previously seen with the woman approached him about a girl on the sidewalk. Security guards held the men who appeared to have blood on their clothes, according to police.
At last check, the woman was listed in critical condition at Advocate Illinois Masonic Hospital.
Police say their investigation is ongoing.
