Five female employees at a high-end mall in New Jersey were found overdosed on suspected fentanyl and revived on Wednesday evening, authorities said.
The women were discovered just after 5:30 p.m. on the first level of the parking garage at The Shops at Riverside mall in Hackensack, FOX5 New York reported.
First responders revived the women using Narcan and CPR, police said. Investigators suspect the women ingested fentanyl before becoming unresponsive.
Four of the women were treated at a local hospital, according to the report. The fifth woman refused medical attention.
