Workers at Newcastle United sponsor Noon have experienced "conditions that may amount to forced labour", a human rights organisation has alleged.
According to research by Equidem, people employed by the online retailer in Saudi Arabia and the United Arab Emirates (UAE) claimed they had been subjected to intimidation and threats, withholding of wages and "abusive" conditions.
Newcastle United declined to comment when contacted by the Local Democracy Reporting Service. The BBC has also approached the club for a comment.
A spokesperson for Noon said the company "strongly refutes" the allegations.
Equidem said its investigators had spoken to 47 current and former Noon workers since March.
