Oklahoma City firefighters responded to a call of a natural gas leak Thursday morning in northeast OKC.
Firefighters responded to F.D. Moon Middle School where some students and teachers were experiencing nausea, but they detected no natural gas leak at the school.
EMSA responders said all patients are OK on scene.
However, OKCFD said it did detect the scent of a leak in the area and are actively searching for the leak at this time.
The school was evacuated as a safety precaution, but students and staff returned just after noon Thursday.
This is a developing story.
