A member of staff at Sydney’s Nepean Hospital says she feared for her life after police shot a knife-wielding man then told patients there could be a bomb. Police officers shot a 54-year-old man at Nepean Hospital on Thursday afternoon after he walked into the emergency department and allegedly threatened a security guard. Tanya Sartori said it was “chaos” when patients were asked to leave the building and were then told by police “there could be a bomb”. “There was a patient next to me on crutches and she was like ‘I can’t walk, where are we meant to go,’ and I said, ‘I have no idea what happened’.” Ms Santori said the police officer told her someone had been shot with a Taser. “Then he came back after going inside and telling everyone to get out and he said we’ve shot someone and there’s a bomb, you’ve got to go,” she said. Ms Santori said there was a commotion as police told people to get away. “I didn’t fear for my life until (the officer) said there’s a bomb or there could be a bomb — that was the main thing. “I was just thinking, ‘is it going to go off, where is it?'” Nepean Hospital reopened early on Friday morning after being in lock down.
