As reported by Wales Online, Mr Winters-Jones was confronted after leaving the Next store.

He was confronted in Marks and Spencer, shortly after he had left the Next shop.
After the assistant accused him of stealing, Mr Winters-Jones said he felt forced to show him the colostomy bag, to prove he was not stealing.
The assistant quickly apologised, and then left.
Speaking to the paper, he said he felt very "shaken up" by the incident and called it a "public shaming".
