THIS is the moment an angry yob went on the rampage inside a Sports Direct store trashing displays and shoving over rails of clothes during an epic meltdown.

Shocking mobile phone footage captures the man ranting with staff as he violently pushes over a stand of t-shirts at the sports shop in Yardley, Birmingham.

But he is soon forced to make a grovelling apology after shoving a stand of golf clubs into the face of a burly customer who then squares up to him.

The customer can be seen repeatedly pushing the man, who is wearing a pink t-shirt, while asking him 'what you doing?' as he makes a hasty retreat telling him 'I'm sorry'.

Another person off camera can be heard saying "bust him in the face wid da ting ya know" as the row escalates in front of families with young children.

Security staff just stand by and do nothing until a middle aged woman steps in to separate the men at the Swan Shopping Centre on Sunday (20/5).

The shocking footage was uploaded to the Birmz Is Grime Instagram page where it has been viewed 10,000 times since being uploaded 24 hours ago.

Bolteye commented: "Instant karma. Thought he was the big man trashing rails of clothes and then forced to apologise when someone his own size gets involved. Serves him right."
