Approaching the iPhone 6 release date, Foxconn is implementing rigorous security inspections targeting workers who produce iPhone 6 in order to prevent them from letting out confidential information about the new product. During the night shift on August 21, 2014, a conflict developed between an assembly worker and a guard due to such an inspection when the worker went to the restroom. Harsh words were shared between them, and the guard stabbed the worker with a knife, killing him. The guard confessed to his crime.
