Four people were taken to hospitals in serious to critical condition after they overdosed in a River North nightclub Sunday morning, according to the Chicago Fire Department.
Fire officials said the overdoses occurred at Y Bar, 224 West Ontario, around 2:50 a.m.
Two men were taken to Rush Hospital and a man and woman were taken to Northwestern Memorial Hospital, according to a tweet on CFD’s official account. The tweet said all four patients were in “red” condition, which generally indicates that immediate life-saving measures are needed.
The fire department did not identify the substance that caused the overdoses. However, officials have been stepping up efforts to warn the public about the spread of fentanyl, an extremely potent and deadly opioid, that has been appearing in counterfeit pills and street drugs.
CFD previously said the overdoses occurred at Sound-Bar, which is located directly next door to Y Bar, but it later issued a correction.
