Another Primark shopper has come forward to say they have found a cry for help note from a worker producing clothing for the company.
The second incident of a note being found claims Chinese prisoners were being made to work 15 hours a day in slave labour conditions making garments.
The note, written in Chinese with 'SOS!' scrawled across the top in English was found with a prison identity card in the pocket of a pair of trousers, bought in Belfast by Karen Wisínska.
The letter explains the prison workers are producing clothes for export all day and "What we eat is even worse than food for pigs and dogs. The work we do is similar to (the hard work) that oxen and horses do.
"We urge the international community to denounce China for this inhumane act," it continues.
According to the BBC, after getting a translation for the note on Facebook, Wisínska said she "felt sick" and then contacted human rights campaigners, Amnesty International.
Amnesty's Northern Ireland programme director, Patrick Corrigan said, "It's very difficult to know whether it's genuine, but the fear has to be that this is just the tip of the iceberg."
Primark are said to be investigating the letter and released a statement saying, "Nine inspections of the supplier have been carried out by Primark's ethical standards team since 2009. To be clear, no prison or other forced labour of any kind was found during these inspections."
Earlier this week another shopped claimed to have found a label sewn into her recent Primark dress purchase saying, "Forced to work exhausting hours." According to Primark, this is also being investigated. What was that about an iceberg?
The issue over the production of Primark's clothes comes a year after 1,100 people were killed when a garment factory collapsed in Bangladesh, where Primark and other high street retailers sourced their clothes.
