Ohio man shot by police officer after allegedly stabbing four in downtown office building

(CBS/AP/WBNS) COLUMBUS, Ohio - Authorities say a man stabbed four people at a downtown Ohio office building and was then shot and wounded by a police officer as he left the building Wednesday afternoon.

Columbus police spokesman Sgt. Rich Weiner says three of the victims are now in critical condition at a downtown hospital, while the fourth received minor injuries.

The attack was reported at about 12:45 p.m. Wednesday at the AT&T building that houses offices of the Ohio attorney general and Miami-Jacobs Career College.

CBS affiliate WBNS reports a female officer shot the man who was the alleged attacker. At least two of the stabbing victims ran outside along with the suspect.

Jim Gilbert, the president of Fraternal Order of Police Lodge No. 9, said that the officer encountered a man outside the building who was wielding two knives and shot him.

"She acted courageously," Gilbert said.

Weiner says police don't know what prompted the attack or whether there's any connection between the suspect and the wounded.

The suspect is in critical condition and his name has not been released.
