“Worst case I’ve ever worked on in my police career” says detective after woman and two men convicted for filming and abusing children


Two men and a woman have been convicted of the ‘horrific’ and ‘sadistic’ abuse of five children over a number of years in the UK.

Lee Calder, 31, of Whittlesey, Peterborough appeared at Peterborough Crown Court on July 23rd via video link where she admitted 14 offences of seven counts of assault of a child under 13 by penetration and four counts of causing or inciting a child under the age of 13 to engage in sexual activity.

She also admitted to 3 counts of obtaining child pornography.

Calder was sentenced to 19 years in custody where she was sent to Hellesden Hospital in Norwich to be treated due to mental health disorders.

Two doctors, Dr Kaiser and Dr Galappathie had both given their assessment of Calder’s mental state, with Dr Galappathie explaining that her “mental health problems made her vulnerable to exploitation” according to Judge Lowe.

Once she is deemed well enough she will join the prison population to continue her sentence.

Her accomplices, partner at the time 29-year-old Guy Delph, and his uncle, 28-year-old Kieran Burton, were both jailed for their parts in the crimes.

The men from Downham Market, Norfolk, admitted abusing four girls aged between three and ten over a period of two years, and a fifth for three years from birth.

Burton also admitted offences including owning a ‘paedophile manual’ containing advice and guidance on the abuse of children and making more than 35,000 indecent images of children.

Delph was sentenced to life in prison, with a minimum term of 12-and-a-half years before being considered for parole.

He had previously admitted rape of a child under 13, four counts of assault of a child under 13 by penetration, four counts of sexual assault of a child under 13, two counts of causing or inciting child prostitution or pornography and taking an indecent photograph of a child.

During his sentencing on 7 May, Delph was branded a “manipulative and dangerous individual” at his sentencing by presiding Judge Lowe at Peterborough Crown Court.

Judge Lowe went on to say that Delph’s manipulation of Calder was “disproportionately successful because of her mental health issues.”

Judge Lowe told the court that he was “not satisfied that Miss Calder presents a significant risk by causing serious harm by committing further serious offences.”

Explaining this reasoning, he said: “I find that these offences arose as a result of her relationship with Delph and not as a result of any pre-existing sexual interest in children.

“If he had not come into her life it is unlikely that these offences would have occurred.”

However, he continued: “That being said, ultimately Miss Calder chose to behave in the way which she did.

“This is not a case where even Miss Calder suggests that there was even a significant degree of coercion, Mr Delph’s manipulation was more nuanced and subtle than that.”

Burton received a 13-year-sentence, of which he must serve a minimum of eight years in prison before being considered for parole.

Peterborough Crown Court was told that during the timeframe of some of the abuse, there was social service involvement with the victims.

Cambridgeshire County Council said there had not been a referral for a review into the abuse.

A spokesman said: “As soon as the allegations were made, Cambridgeshire County Council acted swiftly to support and protect the victims of these offences, and has also worked with police to help bring the prosecution to this conclusion.

“We constantly review our actions; in this case we are content that as soon as we were made aware of allegations, and even before charges were brought, we acted swiftly to protect the victims.”

DC Sian Thomas, from the Child Abuse Investigation and Safeguarding Unit (CAISU), said: “This is the worst case I have ever worked on in my entire 11-year police career.

“The level of sexual offending is the most degrading and sadistic over a sustained period of time, with several different victims.”

Their offences became known in 2018 after Burton was investigated for child pornographic images he uploaded to social media.
