The ruined 17th century Doncaster mansion with links to schoolgirl's murder on sale for £395,000

Drone images show the fragile state of Ivy Farm Manor in Hampole, near Doncaster, which is said to have previously belonged to respected psychiatrist, Dr Neil Silvester.

Pictures show the crumbling and windowless brick walls of the four-bedroom 400-year-old farmhouse - known to the locals as 'The Doctors House' - which has been reclaimed by nature.

Mr Silvestor is known for his fatal mistake involving the early release of 24-year-old Carol Ann Barratt from the psychiatric unit at Doncaster Royal Infirmary.

On March 30, 1991, Barratt was arrested at Frenchgate Shopping Centre in Doncaster for threatening a 12-year-old girl with a knife.

And following an assessment by a police surgeon, an approved social worker and the duty psychiatrist, she was later admitted to the hospital under a section of the Mental Health Act 1983.

During her admission Barratt appealed against her detention to the Mental Health Review Tribunal, but it was later turned down.

But, unexpectedly, just over two weeks later on April 14, the responsible medical officer at the time - Dr Silvester - discharged Barratt, allowing her to walk free from the hospital.

Two days later on April 16, Barratt went back to Frenchgate Shopping Centre and brutally stabbed to death 11-year-old schoolgirl Emma Brodie who was out shopping with her older sister at the time.

A report from a fact finding committee set up by Trent Regional Health Authority to investigate the incident found Dr Silvester's decision "constituted a serious error of clinical judgment".

The report also revealed shocking details that Dr Silvester knew of Barratt's "danger" to the public yet still decided to release her.

The report read: "Although her (Barratt's) responsible medical officer realised her dangerousness he nevertheless decided to discharge her from Section.

"In doing so he expressed the hope that the police would then get involved which could allow for more long-term detention of Carol to be arranged."

It is believed that he moved out of the property in 1991 but continued to practice at Doncaster Royal Infirmary.

Barratt later pleaded guilty to the manslaughter of Emma on the grounds of diminished responsibility.

The house is said to have remained empty ever since and has since fallen into ruin, though it has been listed on the market on a number of occasions.

It is currently on sale with a guide price of £395,000.

The listing says it is not a "listed building".

The property sits on 3.5 acres of land and has a swimming pool and a garage for five cars.

It is also a hit with urban explorers who have found remains of rare sports and saloon cars, psychiatric journals, and 1970s hi-fi magazines.
