John Theriault, Apple’s vice president of global security, has left the company following the controversial lost iPhone 4S investigation earlier this year, reports “9to5Mac” (http://www.9to5Mac.com).

The brouhaha began when an Apple employee reportedly lost a prototype of the upcoming iPhone 4S. Apple reps purportedly visited the home of the device’s purported finder and offered him cash for the return of the phone. Then Apple security officials reportedly posed as police officers in their search of this prototype iPhone, and the San Francisco Police Department are apparently investigating the situation.

Theriault, former vice president of Global Security for Pfizer, joined Apple in 2007. Prior to joining Pfizer, he spent 26 years in the FBI.
