An armed man forced his way into a Saint Louis medical center Saturday Morning.
Saint Louis Police received a call saying a masked intruder had approached a nurse in the hospice center, demanding narcotics.
Reports say the nurse fled as the intruder ran the other direction.
Authorities believe the intruder fled the hospital at this time, in what is said to be a foiled robbery.
The hospital was on lock down until this afternoon.
The suspect remains at large and an investigation has begun.
