One bank security guard and a suspect have been injured in a Central District shooting, the Seattle Police Department Twitter feed reports. The security guard, 46, who is in serious condition, was in a scuffle with the 30-year-old suspect, who is in critical condition with life-threatening injuries. Both men are enroute Harborview Medical Center. The intersection of 23rd Avenue South and South Jackson Street is closed. More details as they come.

UPDATE AT NOON: Police say the shots were fired from the same gun—the security guard's gun. The two got into an altercation and the suspect took the gun and shot the guard; then, police explain somewhat vaguely, the suspect was "also injured by gunfire." It's not clear at this time if the suspect shot himself.
