At approximately 11:30 a.m. today, an unidentified male armed with a knife entered the Edmund S. Muskie Federal Building, 40 Western Ave, Augusta, Maine, and allegedly physically assaulted one of the Federal Protective Service (FPS) guards. Another Federal Protective Service guard then shot the subject. The subject is in custody and has been transported to the hospital.
