FILE - In this May 26, 2010 file photo, staff members work on the production line at the Foxconn complex in the southern Chinese city of Shenzhen, southern China. A workers' rights group has accused another supplier, Pegatron, of violating Chinese labor laws.
Another Chinese manufacturer which produces parts for Apple products has been accused of workers-rights abuses, according to reports.
China-based factories of Taiwanese company Pegatron have committed safety and environmental violations, according to China Labor Watch, the Wall Street Journal reported.
Pegatron factories have been taking up more work from Apple as the company, whose iconic products are produced overseas, shifts work from Foxconn, the newspaper reported.
Among the violations alleged are withholding pay and worker ID cards that would allow the factory workers to seek employment elsewhere, the newspaper reported.
Apple confirmed some of the allegations, the newspaper reported.
Pegatron's factory employs 70,000 people, who produce one-third of the world's iPhones and iPads, the newspaper reported.
Foxconn was found to be in "widespread" violation of Chinese labor laws and Apple's own policies around suppliers last year, the newspaper reported.
Since then, more work shifted to the heretofore smaller Pegatron. Apple said that it will investigate the claims made by China Labor Watch, the newspaper reported.
