Jimmy Savile's brother sexually abused vulnerable patients and raped one at Springfield mental health hospital in Tooting, according to a damning report.

The chief executive of the NHS trust has today issued an apology to the victims of Johnny Savile who worked at the hospital as an “entertainment officer”.

South West London and St George’s Mental Health NHS Trust carried out an investigation into seven historic allegations of sexual abuse by Johnny Savile.

The report said he acted like a "minor celebrity" and used his brother's fame to prey on patients.

Johnny Savile ran the hospital’s radio in the late 70s and even organised a disco at a girls’ school on June 25, 1979.

Update: Victim says she told mental health trust "14 times" before they did anything

One victim recounted how Johnny Savile had touched her in a sexual way when she was an inpatient at Springfield Hospital in 1979.

She said Johnny provided ‘favours to patients’ if they ‘pleased him’. This meant allowing him to touch them in a sexual way.

She described a store room, which in 1979 was used to store mattresses, and said patients would go down there with Johnny Savile.

She claimed the assault on her occurred as part of a culture whereby female patients wanted to stay in Johnny Savile’s ‘good books’ and would allow him to touch them or engage in sexual activity.

She said patients were all receiving the same treatment, by which she meant Johnny Savile would ‘expose himself’ to patients.

Another victim alleged she was sexually assaulted and raped by Johnny Savile in his office on site.

She recalled one occasion when she visited Johnny Savile’s office in 1979.

She said he locked the door, dropped his trousers, forced her to perform oral sex and then wrestled her onto the couch and raped her.

She returned to the day hospital and claimed the staff noted she was disheveled and asked where she had been, but she did not tell them.

Chief executive David Bradley said today was a sad day in the history of the NHS and said: “I offer my heartfelt apologies to the victims of Johnny Savile.

"The investigation's findings of the suffering the victims experienced, and the lack of support they received, is very disturbing to read about today given our much greater awareness of the sexual exploitation and abuse of vulnerable people.

“The abuse these patients were subject to, and the conditions described at Springfield Hospital in 1979 were wholly unacceptable.

"The report also found that there was a missed opportunity to investigate the allegations first made to Springfield Hospital by a victim in 1991.

“Subsequently, when the same victim disclosed the abuse again, her allegations of abuse were not addressed in the way we would now support someone raising similar serious concerns.

"By 2012, the trust was able to respond more sensitively and appropriately to her concerns.”

Johnny Savile worked at Springfield Hospital in the 1970s and he was sacked in 1980 as a result of an allegation made by one of his victims.

But he went on to spend time at Richmond Royal Hospital, where his wife worked in the canteen, and they shared a flat on the edge of the site.

There was also an ex-personnel officer who said he had also spent time at Normansfield Hospital in Teddington, although another witness, described as highly placed and credible does not remember him being there. Johnny Savile died in 1998.

There was no evidence or record of his brother Jimmy Savile ever visiting Springfield Hospital, the trust said.

The trust is asking anyone who has concerns or if they need advice to call them on 0203 513 6150, in confidence.
