Ms O'Neill, was putting equipment into an ambulance when she was injured just before midnight on Monday.
"I was carrying out a routine check on the ambulance just after I had come on duty. I was changing some equipment in the back of the ambulance and suddenly I was hit with a stone just above the right eye.
