A Coles customer has allegedly threatened a security guard after she was accused of shoplifting from a Melbourne store.
The video was shared to Facebook on Monday and shows a customer leaving a Coles supermarket with a trolley full of groceries.
The person who shared the video to Facebook explained the ordeal happened at Derrimut Coles, west of Melbourne.
"Security and staff said she hadn't paid for something in her trolley, they play an awkward tug-o-war for a bit," the post on Facebook said.
The person who shared the video to Facebook also said the woman "threatened" to stab the security guard, and said she pulled out something which "appears to possibly be a knife in a sheath".
Yahoo News Australia understands the woman did not have a knife on her.
In the video, the customer is seen trying to pull the trolley away from the security guard, who is seen wearing a blue shirt.
"Let go," the female customer is heard saying.
After scuffling over the trolley for more than a minute, the woman appears to pull a dark object out of her pocket.
She walked towards the security guard, prompting him to let go of the trolley.
The woman and another person are then seen walking away and towards the exit.
As she makes her way away from the Coles supermarket, the woman is heard saying "f**k off".
It is understood this incident happened last week.
"We were concerned to see this vision and are investigating with the team at the store," Coles said in a statement to Yahoo News Australia.
People on the Facebook post were shocked by the dispute, with one person labelling it as "disgusting".
Yahoo News Australia has contacted Victoria Police for comment.
