A total of 10 students were evaluated Thursday morning after a suspected overdose at Van Nuys Middle School.
Around 11:20 a.m., Los Angeles firefighters responded to the campus at 5435 Vesper Ave., officials said in an alert.
The students, who are 12 to 14 years old, were found to be in “mild-to-moderate distress,” fire officials said in an updated alert.
Seven were taken to local hospitals that specialize in pediatric medicine, while three were released at the scene.
The school was searched for any additional victims, but no students were unaccounted for.
The incident was not fentanyl related, crews at the scene confirmed.
