A McDonald's employee has been arrested for running down a co-worker in her car following a fight that spilled out into the restaurant's parking lot. 

Destiny Allen was charged with aggravated assault and criminal damage to property over the incident, which took place at the fast food franchise in Home Park, Atlanta last Friday night. 

Co-worker Zoe Gunn was left with a broken leg after being struck by Allen's vehicle.  

According to FOX 6, Allen had been embroiled in an altercation with another, unnamed colleague inside the McDonald's just minutes earlier. 

Grainy cell phone video shared by FOX 6 reporter Eric Perry to Twitter shows Allen and the other employee fighting with each other on the floor of the franchise.  

Gunn allegedly intervened and attempted to break up the fight, which then moved outside. 

At that point, Allen got into her car and drove directly into Gunn, which knocked her backwards into a drive-thru window. 

An ambulance rushed to the scene, before Gunn was transported to a local hospital with a broken leg. 

Police arrived and arrested Allen, taking into custody where she was charged.   

Gunn has been shaken up by the incident, according to her sister. 

'If she would have hit my sister harder then she probably would have killed my sister,' Amia Turner told FOX 6. 

'All she does is cry,' Turner added, claiming her sister is now unable to work and has been left homeless.  

'She can't get up and down the stairs. She had to go to a homeless shelter. She's in a homeless shelter right now,' she stated.
