Fentanyl spread through air vents at an Ohio detention center, sending 7 people, including corrections officers, to a hospital, authorities say

• Seven people were transported to the hospital after fentanyl was released through an air vent at a detention center.
• The victims were identified as four juveniles and three corrections officers, authorities told WTVG.

Seven people were transported to the hospital after authorities say fentanyl was released through the air vents at a William County, Ohio juvenile center.

Authorities, including ambulances and the fire department, arrived at Northwest Ohio Juvenile Detention Training and Rehabilitation Center at about 8:30 p.m. on Sunday night, WTOL reported, after receiving a call that some juveniles had collapsed.

At the scene, responding officials found that fentanyl, a synthetic opioid generally used in hospitals to treat pain after surgery, circulated through the vents of the facility, according to the report.

The victims, identified as four juveniles and three corrections officers, were transported for treatment on Sunday night and are in stable condition, Williams County Sheriff's Department Chief Deputy Jeff Lehman told WTVG.

The outlet reported that the other juveniles were transferred to a facility next door, separate from adult inmates, the chief said.

An investigation has been launched into how the drug spread through the ventilation system. The Williams County Sheriff's Department did not immediately respond to Insider's request for comment.

Fentanyl is up to 100 times more potent than morphine and 50 times more than heroin, meaning just two milligrams of it can be deadly, only a fraction of the lethal dose needed for the older opiate, as Insider's Naina Bhardwaj previously reported.
