The organisers of this year's London Olympics said Sunday they were investigating claims that cuddly toy versions of the Games mascots are being made by poorly paid workers in a Chinese factory.
Golden Bear, based in Telford, central England, has a licence to produce Olympic products based on Wenlock and Mandeville, the official mascots of the Olympics and Paralympics.
An inquiry was launched after media reports about the pay and conditions of the workers making the toys at a factory in China.
Golden Bear and the London organisers, LOCOG, said they were taking "seriously" the allegations that workers making the mascots were labouring for more than 11 hours a day for as little as 26 pence (40 US cents, 31 euro cents) an hour .
A London 2012 spokesman said the organisers place a high priority on "environmental, social and ethical issues" when securing goods and services and are taking the allegations "extremely seriously".
He said: "We have asked our independent monitor to carry out a comprehensive investigation and review of these allegations.
"The outcome of this investigation will be made public as soon as it is concluded.
"We have contacted all of our licensees to reiterate to them the importance we place on the sustainable sourcing code they have each signed up to."
Golden Bear said it was also conducting an immediate investigation, but confirmed that the factory in question had passed inspections by the International Council of Toy Industries (ICTI).
The company said in a statement: "Golden Bear is extremely concerned about recent reports that a factory involved in a small amount of the production of the company's Olympic product could be in breach of workers' rights.
"We are a family-run business that takes these issues very seriously indeed and has in place certificates of compliance at all factories used to produce our products.
"We are therefore in the process of conducting an immediate investigation and will be able to comment on these findings as soon as they are known to us."
