A 23-year-old woman was sexually assaulted on Sunday night (July 29th) at the first of two Foo Fighters concerts taking place at Chicago's Wrigley Field. According to the Chicago Tribune, the woman alleged that she was groped while waiting in line for food at the stadium. After leaving the line and walking to a portable toilet, the man followed her and entered the toilet before she could lock the door. She reported being sexually assaulted, with the alleged offender grabbing her neck and hitting her head against the wall.

After the alleged incident, the anonymous female fan reported to the nursing station, where police and an ambulance were called. The suspect was described as white, between 40 and 50 years old, around 5’9″, with thinning brown hair and possibly a receding hairline. Police said that they were currently processing video from the site and that the toilet has been seized as evidence.

Chicago Cubs Vice President of Communications and Community Affairs Julian Green said in a statement, “We are using every available resource to help authorities identify and apprehend the suspect and are working with CPD to address the matter quickly. We are encouraging anyone who may have information to please contact police.” Green noted that security had also been increased in the area where the portable restrooms were located.

At press time, the Foos had been scheduled to play their second show at the historic ballpark on Monday night (July 30th). The Chicago dates are part of the band's current North American run in support of last year's Concrete And Gold album.
