A Gwinnett County mother became irate and made a bomb threat after school officials refused to release her child because the mother didn’t have ID, police said.

It happened just before 2 p.m. Friday at Ferguson Elementary School in the 1700 block of Centerview Drive in Duluth, police said.

The school was placed on lockdown while a bomb squad investigated.

Police said they didn’t find any explosives at the scene.

The mother, identified as Tamika Dena Wolterink, was taken into custody and charged with disruption of a public school and terroristic threats.

The lockdown was lifted and school was dismissed on time, said Gwinnett Count Schools spokesman Jorge Quintana.
