A man was arrested today after he allegedly fired a gun at an Atlanta-area elementary school, sending hundreds of panicked children running out of the building for cover, officials said.

No students at Ronald E. McNair Discovery Learning Academy in Decatur, Ga., were injured and all have been accounted for, Dekalb County School District spokesman Quinn Hudson told ABCNews.com.

A lone white male, believed to be in his 20s and armed with an assault rifle, was arrested this afternoon soon after reports of gunfire, Hudson said.

School officials could not confirm how many rounds were fired, or if the shooting took place inside or outside the school.
