Two men have been jailed for a series of sex attacks dating back to 1975.

The pair were locked up after a jury found them guilty of a number of crimes, including multiple counts of indecent assault, after a four-week trial.

The men cannot be named for legal reasons due to risk of identifying their victims, who are entitled to lifelong anonymity, but are now starting lengthy jail terms behind bars.

The first man, who is aged 80 and is from Wendover, was sentenced to a total of 18 years’ and six months’ imprisonment.

He was found guilty by a unanimous jury of eight counts of indecent assault and seven counts of indecency with a child.

The second man, who is aged 57 and is from Grendon Underwood, was sentenced to a total of 16 years’ imprisonment.

He was found guilty by a unanimous jury of three counts of indecent assault and two counts of sexual intercourse with a girl under the age of 13.

The 80-year-old man’s offences occurred in Aylesbury between 1975 and 1982.

His victims were two boys and a girl.

The 57-year-old man’s offences against a girl occurred in Aylesbury between 1984 and 1988.

The two men were charged with the offences on January 20 this year as part of a lengthy investigation.

Investigating officer detective constable Alex Taylor, of the Thames Valley Police Child Abuse Unit, based in Aylesbury, said: “This has been a protracted and complex investigation over a two-year period into non-recent sexual abuse.

“The victims have shown courage and bravery throughout this case where they have been subjected to horrific sexual abuse as children.

“The sentence given by the court reflects the seriousness of what the victims went through and I hope that they can now find closure and move forwards in their own lives.

“This has been a thorough and successful investigation by Thames Valley Police and I would urge anyone affected by this type of crime to come forward where they can speak to experienced investigators in confidence, and will be fully supported.”
