A man armed with three knives stabbed four people in an office building in downtown Columbus, Ohio. He was shot by responding police officers as he fled the scene.

Sgt. Rich Weiner, a spokesman for the Columbus Police Department reportedly said that a male suspected entered Miami Jacobs Career College, 150 E. Gay St. and had an argument with another male in the admissions office, reported NBC.

Witnesses attempted to subdue the suspect, but three others were stabbed in the process. One of the victims was stabbed attempting to help the first, reported NBC.

We do know that one of the good Samaritans that came to aid the first victim -- he was stabbed also, Weiner said, according to the Associated Press.

The situation eventually moved into the lobby of the building, where a female office responded to emergency calls. Around 12:40, she exited her police cruiser and reportedly saw several wounded victims.

She approached the suspect, who had two knives in each hand, said Sgt. Jim Gilbert, according to NBC. The suspect approached the officer in an aggressive, violent way. The officer responded by firing several shots at the man. The officer was not injured.

He had a knife, and the police had just pulled up, and they're saying, 'Sir, you need to stop. You need to just put the knife down.' He wouldn't. They drew guns. 'Sir, please put the knife down.' And he kind of lunged at them, so they shot him, said Jason Jackson, 31, of Reynoldsburg, who witnessed the shooting, according to the AP.

As other officers began to respond to the scene, they attempted to subdue the suspect. It was reported that needed a taser to apprehend the man. He was taken to Ohio State University's Wexner Medical Center for surgery and is currently in critical condition.

One of the stabbing victims reportedly worked for Attorney General Mike DeWine, who has an office in the building.

The names of those involved have not been released. No motive has been reported.
