Someone tried to set fire to Dothan High School again early Friday morning. The blaze was reported around midnight.
Fire officials and police investigators say several bales of pine-straw had been stacked against one section of the building for a landscaping project and someone set fire to them.
But, firefighters were on the scene quickly and damage to the outside of the cinder-block structure was minor.
Officials say the building where the fire started was used to build props for theatrical performances.
Toilet-paper dispensers in three Dothan High restrooms have been set a-fire during school hours in the past month without causing serious damage.
All of the incidents remain under investigation.
