Several viewers shared a "Code Silver" alert that appears to have been sent to hospital staff indicating that there was an active shooter situation. "Take immediate action to protect yourselves and others," the alert states.

The Medina Township police chief told News 5 that the alert may have been triggered when someone in the professional building next to the hospital said they saw a person with a gun.

Police are searching the building, but have not yet found anything, the police chief said. They are continuing to check room-by-room to clear the building.

Lt. Dave Birckbichler with Medina police confirmed officers are on scene at the hospital. Cleveland Clinic officials confirmed the hospital is on lockdown. Officials have not confirmed that shots have been fired.

News 5 is working to learn more about this developing situation.
