NASHVILLE, Tenn. (AP) -- A Nashville teenager is accused of using a stun device to steal expensive hair extensions from a beauty supply store.

According to Metro Nashville Police, two women entered Hair World Beauty Supply at 3 p.m. on Tuesday. They brought several hair extensions to the register but then tried to leave without paying.

A struggle ensued and one of the suspects used the stun device to shock the employee before they fled with the stolen merchandise.

Nineteen-year-old Keairra Ford was arrested on Thursday and charged with aggravated robbery. A search of the car Ford was driving revealed two empty boxes for stun weapons.

Police are still trying to identify the other woman they believe was involved.

Ford is being held in lieu of $50,000 bail.
