After the incident, the bus driver pulled over and immediately called authorities regarding the spill.

TUSD School Safety, Tucson firefighters and hazmat personnel, and Tucson Police Department responded to the scene.

Students were kept at the scene while their families were contacted. Once the substance was identified, the students were released, according to a TUSD statement.

Officials have not released information regarding any consequences the student might face.
