"Today's actually my birthday and I've got a GP appointment later on this afternoon."
The 29-year-old does not know what provoked the woman.

She said police, who are still investigating, arrived shortly afterwards before paramedics ruled her injuries were so severe she needed to be taken to the hospital to undergo a CT scan.
