An Avondale Estates Elementary parent is in custody after he entered the campus with his gun tucked into his pants.

DeKalb County Schools spokesperson Quinn Hudson said the dad entered the school at approximately 7:10 a.m. He didn’t threaten anyone, Hudson said, but his gun caused the school to immediately initiate lock down procedures.

The parent was arrested and charged with criminal trespass, possession of a firearm on school ground and disrupting a school. When asked if the parent had a permit for the gun, Hudson said, “It doesn’t matter,” saying it is against the law to bring a gun onto school property.

The lock down has been lifted, Hudson said.

Lately all schools are on guard for the possibility of someone entering the school with the intent to harm students and teachers.

The incident follows a hectic week in nearby City Schools of Decatur. School and police officials there are investigating a bullet found on the floor of the boys locker room at the high school and a bomb threat made by an identified male who called the Police Department.
