A student captured a “code red” lockdown inside her Indiana high school classroom after a shooting occurred at a nearby middle school on May 25.

A teacher and a student were injured and a student was in custody after a shooting at Noblesville West Middle School, according to media reports.

A “code red” was called at Noblesville High School for safety and precaution.

In the video, a student films her classmates barricading the door with desks and chairs while a teacher urges her class to stay calm.

“This video was taken at the high school at 10:28 this morning after a ‘code red’ was called at 10:27,” the filmer said. “We had been trained for ALICE drills (Alert, Lockdown, Inform, Counter, Evacuate), which are in case of a school shooter or an event in which the school is in internal danger.”

“They tell us to barricade the door, grab anything we can use as a weapon, such as our books, iPads, phones — anything we could use — and hide in the corner so that you can't be seen from the door window,” the filmer said. “Our class was very fast and piled desk on top of desk in a matter of seconds in front of the door.”

“It lasted about 45 minutes, and we sat in a corner in almost complete silence.”

I took the video myself in Mrs. Anderson's literature and composition class. I am a junior in high school and this video was taken at the High School at 10:28 this morning after a code red was called at 10:27. We had been trained for ALICE drills which are in case of a school shooter or an event in which the school is in internal danger aka the code red. They tell us to barricade the door, grab anything we can use as a weapon such as our books, ipads, phones, anything we could use, and hide in the corner so that you can't be seen from the door window. Our class was very fast and piled desk on top of desk in a matter of seconds in front of the doir.. The code red was called due to a bomb threat yet others said they believed another shooter was in the high school. It lasted about 45 minutes and we sat in a corner in almost complete silence.
