Apple is investigating whether the riot was caused by its Taiwanese iPhone assembler Wistron breaking guidelines over staff pay and working conditions.
at Wistron's plant near Narasapura, India, Apple has announced that it is probing whether the supplier broke its guidelines for the iPhone assembler. According to Reuters, Apple has said that it is cooperating with local police.
"We have teams on the ground," said Apple in an email to Reuters. "[We] have immediately launched a detailed investigation at Wistron's Narasapura facility."
Apple reportedly also said that its teams included auditors, and that it is dedicated to ensuring all workers are treated with dignity and respect.
The protest by some thousands of contract workers concerned both unpaid wages and better working conditions. The rioting caused an estimated $60 million in damages to equipment.
Wistron, has filed a police report accusing more than 5,000 workers and 2,000 further unknown people, of the damage. The company has not commented on Apple's investigation, but said in the filing that it is "deeply shocked" by the violence.
The Narasapura plant is where Wistron has reportedly been recruiting heavily for staff in recent months. The plans were to generate a total of 10,000 jobs at the facility.
