Apple security chief John Theriault reportedly retiring

Apple's vice president of global security, John Theriault, has left the company. In the wake of the investigation into the whereabouts of a lost iPhone 4S prototype earlier this year in which Apple's security personnel allegedly impersonated San Francisco police officers, many believe that kerfuffle was the reason for Theriault's departure.

In that incident, Apple security tracked the lost prototype to a San Francisco home where personnel -- accompanied by real San Francisco police -- were allowed into the home by Sergio Calderón. Mr. Calderón believed the Apple employees were police, and said that he would not have let them in if he had known otherwise.

Both Apple and San Francisco police are investigating what really happened that day, and the company has been in contact with Mr. Calderón. Unfortunately for Apple, the prototype was never recovered.

According to AllThingsD, which confirmed an unsubstantiated rumor first posted on 9to5Mac, Apple isn't saying that the incident is the reason for Mr. Theriault's departure. Instead, they're saying that he has retired from the company, which sounds like a nice way of giving Mr. Theriault a choice between leaving gracefully or being fired.
