A report from Taiwan's Chinese-language Commercial Times claimed Apple had ordered Wistron to stop production of the iPhone 8 plus at a plant in Kunshan, China for two weeks pending a probe into alleged use of water-proof components from a supplier who had not received the blessing of Jobs' Mob.

Wistron has penalised several mid- and high-level executives, hoping to regain Apple's trust, claimed the report.

Wistron told the Taiwan Stock Exchange that the report was pants and there was not a "two-week production suspension as reported and operations remain completely normal".

That could be very carefully worded and does not appear to be widely believed. Wistron's shares dropped by more than five percent during early trading on the Taiwan Stock Exchange; it regained ground to close down by NT$0.45.  However, this might have something to do with he the fact that Wistron is responsible for production for a minor part of the iPhone 8 Plus. Foxconn Electronics (Hon Hai Precision Industry) is the largest maker of the iPhone 8 Plus, producing up to 80 percent of the shiny toy.

Apple is cracking down on suppliers who might be using child labour, or parts made in unsafe working environments.  To be fair, we don't know if Wistron's unauthorised partner, if it exists, did that sort of thing.
