A labour rights group has accused a supplier of Apple in China of misconduct including withholding employees' pay and environmental violations.

The report by China Labour Watch said it found violations of the law and of Apple's pledges about working conditions at facilities operated by Pegatron, a Taiwanese electronics manufacturing company.

Apple said in a statement it was “committed to providing safe and fair working conditions” and would investigate the claims.

Pegatron, in a separate statement, also promised to investigate.

Apple said an investigator for the company confirmed one accusation by China Labour Watch — that Pegatron was holding the identity cards of some workers — and ordered the company to stop.
