Mystery Powder Prompts Apple Building Evacuation

Apple employees were evacuated from one of the company's Cupertino campus buildings on Wednesday after an envelope with a white powder inside was discovered. Initial tests showed the powder was not hazardous, but the Santa Clara County Sheriff's Department still plans to run additional tests, according to the San Jose Mercury News.

County fire fighters evacuated Building 4 on De Anza Blvd around 3:30PM after receiving a call about the suspicious envelope. Additional details about the envelope and the powder inside are still unavailable.
