Police responded to the hospital for an active threat, said Ted Czech, public information officer for the York County Office of Emergency Management.

A gunman was killed after shots were fired at UPMC Memorial Hospital in York County, Pennsylvania on Saturday, a hospital official told the Associated Press. Officials with UPMC told CBS News that a gunman was at the hospital and was "apprehended" after shots were fired. No patients were hurt, UPMC said in an emailed statement.

Officials with York County's Office of Emergency Management said officers responded to a "threat" Saturday morning at the hospital located on Innovation Drive, but that threat has since been "neutralized".
