A possible gas leak at a building in Escondido prompted fire officials to evacuate a building filled with roughly 150 people.
Twelve patients complained of a noxious odor in the Graybill Medical Clinic located at 225 E 2nd Ave. Three offices were effected on second floor of the building.
Originally four people complained of being nauseated, weak and dizzy. After fire officials evacuated the building, eight more people complained of similar symptoms.
All patients were checked, but not transported to a hospital as they felt better once they got some fresh air.
The HAZMAT crew from County Department of Environmental services could not find a source that was making people sick, according to Escondido Fire Department Battalion Chief John Tenger.
The building is open for business on Tuesday.
