A Texas school district has shut down all of its campuses over an alleged shooting plot foiled just one day after the massacre in Uvalde, according to reports.

The Donna Independent School District said Tuesday that it had received a “credible threat of violence that is currently under investigation.”

“In light of the recent events and in an abundance of caution, we will be canceling school district-wide classes and staff will work from home,” the district said.

“The safety and security of our students & staff is our first priority,” it added.

The district closed down Thursday and Friday. Classes are expected to resume Tuesday, following the Memorial Day weekend.

Police found an AK-47 and a “hit list of targeted students in the suspect’s home,” a source familiar with the matter told local news outlet MyRGV.com.

Two or three people were involved in the foiled plot, according to the outlet.

Donna is about 280 miles south of Uvalde, where gunman Salvador Ramos, 18, went on a rampage at Robb Elementary School on Tuesday, killing 19 children and two teachers.

The Donna Police Department did not immediately respond to comment about the threat and possible arrests.

The school district earlier announced that backpacks would not be allowed at any of the campuses and that access would be limited to guardians with proper identification.

“As the end of the school year draws near, we want you to know that protecting our students, staff and faculty are our top priority and we will continue to take all necessary measures to ensure that our campuses continue to remain safe,” the district said in a release cited by ValleyCentral.com.
