The smell was believed to be coming from an office or classroom at the school located on 101 S. 2nd St. (map), according to Lt. Dan Rodriguez of the Alhambra Police Department.
All staff and students were taken to the track field while authorities worked to determine the source of the smell and whether it was safe to return to the classrooms, Rodriguez said.
