Photo released of man suspected of sexually assaulting woman during Foo Fighters concert at Wrigley

CHICAGO -- Chicago police released a photo Tuesday of the man suspected of sexually assaulting a woman during a concert at Wrigley Field.

The incident happened around 9:30 p.m. Sunday during a Foo Fighters concert. Police said the 23-year-old woman was standing in a line for food when a man groped her. The woman left the line to use a portable toilet and before she could lock the door, the man followed her inside and sexually assaulted her. He then fled the scene.

The Chicago Tribune reported that the attacker grabbed the woman by her neck and hit her head against the wall of the portable toilet. She was later taken to a local hospital.

Law enforcement sources told WGN that new video has been found that shows the two in a 10-minute conversation. Sources said detectives will need to reinterview the woman to try and learn more about their initial encounter.

As part of the investigation, police seized the portable toilet as evidence.

In response to the sexual assault report at last night’s concert, the Cubs added more security by the portable toilets and elsewhere at the ballpark.

The man is described as a white male with a shaved head, between 30-45-years of age, about 6-feet tall and approximately 200-220 pounds. Photos of the suspect were released after detectives checked video in the area.

Police are urging anyone who recognizes this man to please contact Area North Detectives at: (312) 744-8261
