A paedophile businessman has been jailed for five years after sexually assaulting a three-year-old toddler.
Former company chief executive Brian Hall videoed himself touching the tot and saved the sickening films onto his laptop.
He also had online chats with other perverts, pretending to be a 13-year-old girl.
Hall’s home at Moorthorpe Rise, Owlthorpe, was raided by police in 2014 after detectives got a tip-off from the National Crime Agency that a computer at that address was being used to access and distribute indecent images.
A laptop and other items were seized. An analysis revealed the devices contained a total of over 600 indecent images of children.
The laptop contained the video of Hall, former chief executive of an engineering firm, sexually assaulting the three-year-old.
Giles Bridge, prosecuting at Sheffield Crown Court said: “I have spoken to her family. She has no recollection of the events and hasn’t been told of them.
“The family themselves are very upset about what has happened but they have moved on as best they can.”
Detectives also found 101 emails Hall sent pretending to be a 13-year-old girl.
Mr Bridge said: “He was interviewed and asked about his use of filesharing software. He said he used it to download indecent images of children and had been doing it for five to six years.
“He said he was disgusted at what he had done and was waiting for the police to come.”
Andrew Swaby, defending, said Hall had sought assistance from a therapist and was suffering with mental health problems.
He said: “He had never previously come to the attention of the police.
“Mr Hall has had great difficulties in speaking openly about his offending. He accepts full responsibility.
“There’s another side to this gentleman. There are a number of professional references that speak of him in glowing terms.
“He can’t offer any real explanation as to how this started. He knows it is unacceptable, it’s appalling what he has done.
“He has lost the faith of family and friends.”
Sentencing him to five years in prison, Judge Michael Murphy said: “Your family has broken down and you have no doubt lost your position in society.
“It must have been a sickening experience for the family of the three-year-old child. I don’t know what effect it’s going to have on that family in terms of trusting anyone in the future. What you did to her was inexcusable.
“To distribute this kind of filth encourages and perpetrates the worst kind of child abuse one can possibly imagine.”
Hall admitted sexual assault on a child under 13, and possession and distribution of indecent images.
