A shirtless supermarket shopper has been captured on security footage chasing an alleged shoplifter out of the store.
The customer was buying a gift for his mum at the Hackham IGA supermarket in the outer metro area of Adelaide, South Australia, on Sunday when he stepped in to help staff, Nine News reported.
Another shopper allegedly refused to pay for items he had brought to the counter, with owner Baggio Wang telling the network he "was screaming, yelling, abusing all the staff".
Footage from inside the store showed the alleged robber get into a tussle with the shopper, during which his shirt gets ripped over his head.
The shirtless shopper was then shown retreating into a back storeroom area, where he grabs a machete, usually used to cut fruit.
While holding the large blade, he then runs towards the alleged shoplifter, who backs away before running towards the exit of the store.
Mr Wang described the shirtless shopper a "nice guy" who had been trying to buy gifts for Mother's Day before becoming involved with the alleged thief.
He added the 15-year-old girl who tried serving the aggressive man before the brawl had been left shaken.
"I feel really sorry for her because she's a really young girl and shouldn't be dealing with things like this," he said.
Fortunately no one was injured during the ordeal, which unfolded in front of other shoppers on Sunday afternoon.
Police are investigating the incident.
