A Norwich woman was left with a bleeding mouth after finding glass in a supermarket side dish.

The Smith family ordered a ready prepared red cabbage product on online delivery from Sainsbury's in Pound Lane on Friday August 31 for their Sunday roast.

Instead they were substituted with Rumbledethumps - a Scottish dish containing potato, swede and savoy cabbage topped with cheese.

But the family got an extra ingredient they definitely didn't want when they found a piece of glass lurking in the dish.

Matt Smith said: 'The product was Sainsbury's Rumbledethumps and my wife found it by biting into it which caused her mouth to bleed for about five minutes.

'She was obviously a bit upset and it put all of us off our Sunday lunch a bit.'

After making the dangerous find, Mr Smith sent an email to Sainsbury's on Monday and claims he didn't receive a response from the supermarket.

After being contacted by this paper, the supermarket has asked Mr Smith to take the product into store for investigation.
