A doctor already in jail for raping children as young as eleven has been convicted of sexually assaulting three more girls while their parents waited outside his office.
Robert Wells, 65, was jailed for 15 years in 2004 after he drugged two sisters, aged five and eleven, then filmed himself sexually assaulting the older girl.
Another 11-year-old girl also told police that he strapped her to a polystyrene block he called Satan's pillow and filmed himself raping her in his mobile home.
Wells has now admitted four more counts of indecent assault after three victims came forward about abuse that took place beforehand, in the 1980s.

Cardiff Crown Court heard how he was seen as 'an upstanding pillar of the community' during his time as a GP at Caerleon Surgery, Wales.
Prosecutor Matthew Roberts told the court the defendant would ask the children's parents to wait outside his consulting room while he examined them.
When he was arrested, Wells told police he had treated more than 600 patients during his career and could not remember each one individually.
Mr Roberts said: 'It is hard to imagine a more serious and grotesque breach of trust.'
Roberts was jailed at Winchester Crown Court for rapes committed while he worked for an agency providing on-call forensic medical examiners for Hampshire Police.
He had previously had sexual assault charges brought against him but they had not shown up on police checks because he had been cleared when the trial collapsed.
Wells was arrested after he drugged two sisters, aged five and 11, and their mother became suspicious and reported him to police.
The eldest girl had large amounts of benzodiazepine in her body and the younger girl tested positive for temazepam.

Police found both drugs present in his biscuit tin when they raided his home. They also found a timetable for drugging, filming and abusing the children.
Officers then spoke to other families he had befriended, which was when another 11-year-old girl reported yet more shocking abuse.
She told police that he strapped her to a polystyrene block he called Satn's pillow as he removed her Harry Potter pajamas then sexually assaulted her.
He also made her dress up as a French maid, filmed her and massaged her with baby oil, the court heard.
Police found shocking pornography on his computers, along with the video camera and polystyrene block in his mobile phone.
Police, who were struggling to access certain information on his computer, said they feared there may be more victims and urged them to come forward.
The victims in the most recent case came forward after hearing of his 2004 conviction, and relate to his time as a GP in the 1980s, before the other assaults.
The court heard how the charges related to three girls who were Wells' patients, one of whom was driven to the brink of suicide by the emotional impact of the assault.
In a statement read out in court, one victim said: 'He has destroyed my life.'

One victim said the abuse had affected her ability to form relationships and caused her to suffer from depression.
Another described the ordeal as 'terrifying' and said she had developed post-traumatic stress disorder.
The third stated the abuse had caused her to self-harm and attempt to kill herself.
She said Wells had been regarded as an 'upstanding pillar of the community'.
Wells was a registered medical practitioner at the time, but has since been struck off by the General Medical Council.
One of the girl's mothers had made a complaint to Caerleon Surgery at the time, but it was 'arrogantly dismissed', and she was 'told not to be so silly', Mr Roberts told the court.
He described it as a 'gross failing of the system in the 1980s'.
Mr Roberts said: 'All three suffered sexual abuse as children under the pretext of medical examination.'

He added: 'He left South Wales in the late 1980s and went on to commit a series of depraved offences.
'The bond of trust between a doctor and a patient must be sacrosanct.'
The defendant, from Cwmbran, pleaded guilty to four counts of indecent assault after the case was listed for trial.

Ieuan Rees, mitigating, stressed that meant the victims did not have to give evidence.
Judge Jeremy Jenkins described the offending as a 'gross breach of trust' and noted the effect on each victim had been 'long-lasting and profound'.
He added: 'In short, it was done for your own perverted sexual pleasure. It has destroyed their trust in the profession.'
Wells was jailed for seven years and an indefinite Sexual Harm Prevention Order was imposed.
Detective Constable Chris Jayne, from Gwent Police, said: 'I would like to take the opportunity to recognise the bravery of the victims and their families in this case.
'Wells is a danger to children and the detrimental impact that he has brought to the lives of the victims from a young age through to adulthood has been incredibly significant.
'He abused his position of trust as a doctor in the most sinister and opportunistic way against his victims whom he should have been protecting and keeping safe.
'I hope the sentence given will help to bring some closure for the victims affected and their families.'
