A 13-year-old’s apparent fentanyl overdose prompted the evacuation of a school in Connecticut on Thursday.

Officials said a seventh-grader at a Hartford Public Schools middle school collapsed at the gymnasium from the apparent overdose, NBC News reported.

"It is believed that the student ingested something in the classroom," Hartford Public Schools Superintendent Leslie Torres-Rodriguez said in a press conference.

Police from multiple agencies evacuated the campus and were searching the Sport and Medical Sciences Academy after the incident. 

"Our entire community is praying for this child in the hospital and for his family. And again [I] make an ask of every parent to talk with your kids and make sure they know how serious and how dangerous any unknown substance can be and any drug can be," Hartford Mayor Luke Bronin said, according to NBC News. 

"Please have that conversation tonight. We're talking about seventh graders. It's never too early to have that conversation,” Bronin added.

The school has not said if classes will resume Friday.
