The Chicago Ridge Mall opened on time at 11 a.m. Sunday.
Chaos erupted inside the southwest suburban mall food court Saturday night, that led to a large police response and some evacuations.
It happened shortly after 6 in the evening.
Police say there was a fight involving dozens of teens in the mall's food court.
There were additional calls of possible shots fired, but investigators tell WGN they have not been able to confirm those reports.
Police closed the mall by 7pm, hours before it was scheduled to close for the night.
No injuries were reported.
Shortly before 9 p.m. Saturday, Chicago Ridge Police released the following statement:
"At approximately 6 pm this evening the Chicago Ridge Police Department responded to a fight in progress at Chicago Ridge Mall in the food court area. While en route, there was a report of shots fired, and a multi-jurisdictional response was called. Upon arrival several groups previously within the food court area had begun to go into the mall area. Numerous stores closed their gates, and in joint cooperation, Chicago Ridge Police and Chicago Ridge mall security determined that the mall should close to prevent any further entry into the mall by individuals in the original incident. With the cooperation of numerous surrounding communities, the mall was evacuated and remained closed until its regularly scheduled closing time.
Chief Robert Pyznarski states that there were no reports of injuries, and no arrests were made. An on-going investigation is underway regarding the allegations of shots fired."
