Students were evacuated from Scripps Ranch High School Thursday after an odor of natural gas filled the air near the campus.
Hundreds of students filled the baseball fields around 11:00 a.m. when the school alerted teachers to evacuate their classrooms.
A San Diego Fire and Rescue spokesperson reported that fire crews searched the area along Treena Street and could not find a leak.
Students were told to return to class within 30 minutes.
