JIMMY Savile sexually abused a girl at Prestwich Psychiatric Hospital — and threatened that he would have her locked up there if she told anyone about it, according to a shocking report.

The report, published by the Greater Manchester West Mental Health NHS Foundation Trust, refers to a woman known only as Mrs C, who was aged seven or eight at the time.

A separate report by the Central Manchester University Hospitals NHS Trust states that the girl was also abused at the now demolished Booth Hall hospital in Blackley in 1959 or 1960, after Savile was invited onto the ward by her own father following routine surgery.

She alleges that Savile brought her to the Prestwich hospital site and sexually abused her, in or around 1960, before he became a TV celebrity.

The report states that although there were no witnesses to verify or refute the woman’s account, it says the “alleged incidents are likely to have occurred”.

Mrs C alleges that she was taken into an empty ward by Savile and was sexually abused by him and another man.

In a separate incident, she also says that she was taken to the hospital as a threat to discourage her from revealing the abuse.

In a call between her and the Metropolitan Police in November last year, Mrs C describes the scene during the incident.

She said: “The ward smelled horrible, had excrement everywhere and had within it naked male patients.”

The report states: “The visit was used as a threat to her in so far as if she disclosed the abuse she was being subjected to she would be brought back to the hospital and locked away with the patients.”

It continues: “Ms C alleges she was told by Savile that if she ever told anyone about the abuse she was suffering she would be brought back and locked in the room with the men.”

According to the report, it would have been “feasible” for Savile to have brought Mrs C onto the site without being stopped or challenged, because there was no perimeter security.

The trust says that a review of current practice found that there is a “strong deterrent” to similar incidents happening today, due to a “detailed policy framework covering safeguarding arrangements, security management provisions and employment checking processes”.
