The former employee, Xiaolang Zhang, was arrested trying to flee to China and questioned by the FBI regarding the theft of Apple's intellectual property, a crime to which he confessed. Apple has brought criminal charges against Zhang, and he could face up to 10 years imprisonment and a $250,000 fine.

Zhang was hired in 2015 to work on Apple's self-driving car project designing and testing circuit boards that would analyze sensor data. In April of 2018, he took a period of family leave around the time of the birth of his son, during which he visited China. When he got back, he informed his boss that he was quitting Apple and going to China to work for an autonomous vehicle startup called XMotors.
