A woman from Leytonstone suffered six puncture wounds when she was charged at by a male deer she described as having “huge” antlers last Friday.
Yuan Li, 43, was photographing the deer alongside a mother and child when she was attacked.
On assessment doctors also discovered a small blood clot on her bladder, which resulted from the attack.
Ms Li is now calling for Richmond council to erect special enclosures for deer to protect members of the public from further attacks.
Adam Curtis, Park Manager for Richmond Park said: “We’re very sorry to hear a woman has been injured and we hope she makes a speedy recovery.
“This is a frightening accident, and a powerful warning to others why it is dangerous to crowd deer, especially during the autumn rutting season. We’ve prominent warning signs at key locations asking people to stay at least 50 metres away from deer.”
