Six people were arrested Wednesday during two separate incidents at Martin Luther King Jr. High School, both of which resulted in the school being locked down.

The first incident happened when, according to the DeKalb County school system, two males, one of whom was a student, were arrested after reports of a weapon on premise. The second male, who was not a student, was found to be in possession of a firearm.

"Earlier reports about a parent entering the premises with a gun were inaccurate," the system said on Wednesday afternoon.

The second incident involved a stolen car that was tracked to the school parking lot by DeKalb police. "Following a foot chase, four individuals were apprehended and arrested," the school system said. "The theft occurred off school grounds."

The system said the two incidents happened around the same time, but are not related.

"During the lockdown, public safety officers thoroughly searched the building for intruders and weapons," the system said. "Nothing was found and the lockdown was lifted around 11:30 a.m., with students resuming their normal school schedule."
