Margo Lauree-Grant, 41, was arrested Wednesday after allegedly stealing a Canadian man’s Diamond Master during a screening on Aug. 26.
The watch was recovered in pieces.
Lauree-Grant, of Montauk Avenue in Brooklyn, was charged with grand larceny, possession of stolen property and official misconduct.
Her bust marks the second time a TSA agent was arrested this week.
Previously, a TSA agent was arrested at La Guardia airport for sexually assaulting a South Korean college student after allegedly luring her into a bathroom for unauthorized screening.
