According to ABC7, an argument between a 34-year-old woman and a 29-year-old man with another attendee preceded the stabbing.

The argument began at a concession stand within the Huntington Bank Pavilion and continued into the venue itself, where a man pulled out a knife, according to investigators.

He was taken into custody as the attacker. Both victims were treated at Northwestern Memorial Hospital.

The concerted was promoted by LiveNation who hired Monterrey Security to handle crowd safety and protection for the concert, who reportedly uses handheld wands to detect an metallic and illicit material on concertgoers.

Tom King, the Chicago Park District General Counsel, is questioning LiveNation and Monterrey on how an attendee was able to bring a knife into the venue.

LiveNation released a statement following the incident:

“We are reviewing our search procedures and working with the Chicago Police Department to better understand the circumstances surrounding the incident and to ensure that we are following the most appropriate security practices at the venue.”
