AUGUSTA — An abbreviated text message on a state mail-delivery truck driver's official unlisted cell phone had police scrambling for several hours this morning.

Maine Capitol Security Chief Russell Gauvin said the driver received a text message that read “Stcks poised to explode, ticker FDKE, Fred.”

Gauvin said the driver brought the phone to his Capitol Security office in the state’s Cross Office Building just west of the Statehouse.

Gauvin alerted the state Computer Crimes Task Force, which determined after several hours and a subpoena to U.S. Cellular that the message was an advertising message referring to stock trading, not an explosive.

Gauvin said he seized the phone from the driver and kept it for investigation, but he said when the driver returned to his office at the Muskie Federal Building, postal officials there decided to isolate the truck and have it searched with the assistance of an Augusta Police Department bomb-sniffing dog and State Police.

A portion of the Muskie building’s parking was closed off as a precaution until the search was completed.
