Child sex offender preyed on 'very young and vulnerable' Milton Keynes girl for four years in 'complex and distressing' case
A child sex offender who committed indecent assaults and gross indecency offences in Milton Keynes in what police described as a 'distressing’ case has been jailed for 18 years.
Peter Cox, 66, of Brambling Way, Oxford, was jailed after pleading guilty at Amersham Crown Court to six counts of indecent assault on a girl under the age of 14, two counts of gross indecency with a girl under the age of 14, and two counts of gross indecency with a girl under the age of 16.
Thames Valley Police said that Cox received a special custodial sentence for offenders of particular concern, meaning he will serve his full custodial term in prison without automatic early release, which would be followed by a mandatory two-year extended licence period.
Police said that the offending took place in Milton Keynes between 1998 and 2002, and that the victim was a child at the time of the offences.
Cox was first arrested in September 2018 and was charged following what police described as ‘a complex and protracted investigation’ in November 2025.
Specialist investigator Jo Simmons from Thames Valley Police’s Child Abuse Investigation Unit said following the sentencing: “This was an especially distressing case, not only because of the nature of the offences, but due to the victim’s vulnerability and very young age at the time.
“I would like to commend the victim for the immense courage and resilience she has shown throughout what has been a long and difficult investigation.
“Coming forward and supporting a case like this is never easy, and her strength has been truly remarkable.
“I hope this outcome provides some sense of justice and demonstrates that we will always take allegations of this nature seriously, no matter how much time has passed.”
