A US private school is selling bulletproof panels for children to insert in their backpacks in case of a mass shooting.

The Florida Christian School in Miami say the panels give children “another level of protection in the event of an active shooter”.

Parents can order the ballistic panels for $120 (£90) on the school’s website, under a section also promoting the school’s red T-shirts and winter wear for students.

George Gulla, head of security at the school, told the Miami Herald the panels would protect the students’ “centre mass”.

“It’s just a tool,” he said. “I’d rather be prepared for the worst than be stuck after saying ‘Wow, I wish we would’ve done that.’

“We thought, yeah, let’s offer it to anyone who wants it. It’s not required. But it gives you extra peace of mind.”

He added: “It’s out of the norm, but what is the norm?”
