Officials have stopped a man who they say was plotting a terror attack in San Francisco over the Christmas holidays.

The FBI arrested Everitt Aaron Jameson, who is a tow truck driver and lives in Modesto, reported ABC television.

According to FBI documents, the suspect reportedly picked the Pier 39 location because he “had been there before and knew it was a heavily crowded area.” 

Jameson appeared in court Friday, but did not enter a plea.

An investigation is underway.
