At least three people were killed and two others were injured Thursday after a gunman opened fire at a bank’s headquarters in downtown Cincinnati, officials said.

The gunman opened fire at the loading dock and lobby area of the Fifth Third Center in the city’s Fountain Square around 9:10 a.m., Cincinnati Police Chief Eliot Isaac said in a news conference.

The gunman, who has not been identified, was killed after he exchanged gunfire with three to four police officers. One person died at the scene.

One person wounded was said to be in serious condition while the other is in critical.

“The gunman was actively shooting at innocent victims, it appears, and our officers were able to kill him and stop the threat,” Cincinnati Mayor John Cranley said.

Cranley noted the building, which is the corporate headquarters of the Fifth Third Bank, also houses popular ice cream, sandwich and pastry shops. He added that the shooting “could have been much, much worse” if not for the immediate police response to end the threat.

Isaac said there is no additional threat in the area and praised officers for their “quick response.” No officers were injured in the incident.

Authorities were called to the scene in Fountain Square for an “active shooter” situation. Videos and photos taken from witnesses showed multiple patrol cars at the scene. One photo showed a bloodied man being taken away on a stretcher.

A manager at Fifth Third Bank said the shooting left employees “a bit rattled.”

“We did hear a gun shooting from the 29th floor. We could quickly see there was a large police presence and could see them blocking Fountain Square. We knew immediately something was wrong. We’re a bit rattled,” the manager said.

Ohio Governor John Kasich called the shooting “senseless” and commended officials’ swift response.

“There was a senseless act of gun violence on the streets of Cincinnati this morning. I’ve spoken with the Mayor and informed him the state will provide any necessary resources to the local police,” Kasich said. “I commend the law enforcement, fire and EMS personnel who swiftly responded to the scene and share my deepest sympathies with the innocent victims of this violent attack.”
