A seasonal scent sends people scrambling from a high school in Baltimore.

FOX's Chris Foster reports:

Cristo Rey Jesuit School in Baltimore was evacuated Thursday afternoon with several people reporting breathing problems, five hospitalized with upset stomachs. Students and teachers reported a strong smell on the third floor.

A hazmat team responded and ran tests, nothing came up. Firefighters started opening windows to air the place out, finding a pumpkin spice aerosol air freshener plugged into an outlet in a classroom.

The school's back open.
