BALTIMORE, MD (AP) --- Baltimore police say they're setting up a tactical operation to deal with a gunman who is holed up on the eighth floor of Johns Hopkins hospital after shooting a doctor.
A spokesman for Johns Hopkins hospital in Baltimore earlier said the gunman had been caught, but police spokesman Anthony Guglielmi says that's not the case.
Guglielmi says some parts of the hospital are being evacuated, but not the entire massive complex in east Baltimore.
He says he doesn't know the doctor's condition.
With more than 30,000 employees, Johns Hopkins Medicine is among Maryland's largest private employers and the largest in Baltimore.
