Mrs Makaronas suffered bruises and scars to her face and arms and was checked over at the Accident and Emergency department.

She tried to file a complaint about the conduct of the student but was told it was a matter for the police rather than NHS Tayside.

She told the Evening Telegraph she was shocked by the response she received and felt staff were avoiding their responsibility.

She said, “I was walking along the footpath after visiting my new twin grandchildren, when this young chap came charging towards me at a high speed.

“I tried to jump out the way but he slammed in to me. I was totally shocked and taken aback. I have a black eye, swollen face and bruised arm and hands.

“I returned to Ninewells and when I tried to file a complaint the receptionist I spoke to said she didn’t know how to fill in a complaints form.

“I spoke to a woman on the phone and arranged to meet her. But when we met she said the matter was a police issue and had nothing to do with Ninewells.

“They are completely passing the buck here despite the fact all the signs were put up by the hospital and the path was in the grounds.

“I am not after blood I just think action should be taken to address the terrible response of staff and a reprimand to the boy and make sure he know the rules.

“Although I’m a retired lady I’m not unable. But I could have been severely hurt if I was. The public should know this. I am very angry.”

Shona Singers, head of communications for NHS Tayside said, “We took advice from the police following this incident.

“The advice was if the lady wanted to report the incident she should contact the police.”
