A mum was "shocked and worried" after finding what she believed to be blood on a new pair of knickers she bought from Tesco for her two-year-old daughter.
Rachel Davies, 28, said she "wasn't happy" about the incident and hopes to hear more about what the 'stain' on the Peppa Pig underwear was.
She says she made the discovery after buying the underwear for her daughter, Melissa Kocaoz, at the Upperboat store in Pontypridd, Wales.
Rachel took the purchase back to the Tesco store where she said staff were both helpful and apologetic.
Tesco says it is 'sorry' to hear about the incident and is investigating what happened, Wales Online reports.

Rachel's daughter was about to turn two so she bought the new underwear earlier this year, but the mum says she didn't actually open the pack until about a month ago.
Rachel said: "I think I bought them back in April. I bought them then, but I actually opened them later in August.
"It was the last one in the packet. It looked like blood.
"It was on the actual pantyliner bit. I was just shocked and worried."
She said when she returned the purchase to the store, staff refunded the money - but she hopes to hear more about what the stain actually was.
"I returned them and they said sorry," Rachel added.

"A week or two later HQ contacted me and basically said sorry, and I said: 'Are you going to do anything, because it's a big thing, because it looks like blood on a two-year old's underwear'.
"I wasn't happy."
Rachel also said she was told there may be a delay in finding out what happened due to the coronavirus pandemic.
Speaking on Thursday, August 27 Rachel told Wales Live: "I called up this morning, and the person said she couldn't find the case.
"She said she looked three times."
A Tesco spokesman said: “We were sorry to hear about this.
"We received the product back from Ms Davies earlier this month and we are currently investigating what happened.”
