The mother of a Bronx elementary school student was arrested after threatened to commit a shooting massacre, the NY Post reported Friday.

Josette Smalls, 36, blamed staff at PS 48 Joseph R. Drake for her losing her cell phone, police alleged.

“If I don’t get my phone back, I’m going to come back and shoot up the school!” Smalls allegedly claimed. “No child is safe because what happened in Texas and Florida is going to happen here!”

Smalls was charged with making terroristic threats and released on her own recognizance.
