A Thurcroft woman is in a critical condition after falling from her horse as youths pelted it with stones.
Police want witnesses to come forward after the incident at around 5.45pm on Saturday 17th May.
It happened on a track near to Duke of Norfolk Lane, at Wickersley, Rotherham.
The 28-year-old was riding a large, white horse when the group of three or four youths threw stones at the animal, causing it to rear up and throw her to the ground.
Friends came to the injured woman’s rescue. She was treated by paramedics and taken to hospital with serious injuries.
On Monday 19th May, after a number of tests and observation, she was allowed home, but was readmitted the next day suffering headaches.
She was later transferred to Sheffield’s Royal Hallamshire Hospital, where she underwent surgery and remains in a critical condition.
Officers have carried out enquiries in the Wickersley area in a bid to trace the youths, including a search on the day of the incident.
But so far they have been unable to find those involved.
Now they are turning to the public for help.
“We are urging anyone who might have seen what happened or who has any information about the incident to come forward,” said Detective Inspector Steve Ashmore, of South Yorkshire Police.
“We’re also interested in hearing from anyone who has suffered similar problems in the area and will be visiting local stables.”
“This incident shows the serious consequences of antisocial behaviour.”
Any witnesses or anyone with information should contact South Yorkshire Police on 101 and quote incident number 1204 of 17th May.
