GRANDVIEW, Mo. -- Everyone is safe, but an investigation is underway after a gun was discharged at Grandview High School Wednesday.
Administrators say a student brought a backpack to school with a gun in it. That backpack was dropped inside of the PE locker room, and the gun accidentally discharged.
According to the district no one was injured.
"Immediately after the report students were evacuated from the area and all students were held safely in their classrooms as Grandview Police were called to investigate," Grandview School District spokesperson Sheba Clarke said. "During that process the school went into an external lockdown until police were able to secure the gun."
As of 11:20 a.m. the gun was secure, and the investigative process had begun. The student who brought the gun to school was also being questioned.
"They were saying we couldn't go into school because the school was on lockdown," student Tim Burks told FOX 4's Shannon O'Brien who was at the scene.
Burks said this was the first time he's heard of someone bringing a gun to Grandview High School.
"The safety of our students and staff is our top priority," Clarke added. "Currently an investigation is in process and student discipline will take place according to board policy and statute. "
Elijah Wright, who was inside the school at the time the lockdown went into effect said teachers were doing what they were trained to do.
"They said lock the doors, get away from the doors, the windows and everything," Wright said. "The teachers did amazing when it comes to that. They locked all the doors. They told us to get away from the windows and doors."
Wright says teachers remained calm while responding.
"It didn't take long for me to notice what was happening because it was on Facebook," Wright added. "As another student did post it. That's how I found out what was going on, but the teachers were just like relax, have a seat, we're just going to put on a movie and we'll just go from there."
"No one was freaking out," Wright added. "The students were concerned about what was going on, and they were questioning it. But everyone was calm. No one was shouting or freaked out."
In early December 2016 a deadly weapon was found inside the halls of a Grandview elementary school. An investigation revealed that a second grader at Conn West Elementary brought a gun to school. Read more on the startling discovery the second grader made.
