The offences were committed by David Bolton, from East Bowling, over a period of more than thirty years.
A Bradford pensioner is likely to spend the rest of his life behind bars after being found guilty of sexual offences against children.
David Bolton, aged 77, was sentenced to 22 years at Bradford Crown Court on Friday after a jury had found him guilty of six counts of rape, seven sexual assaults and an indecent assault, following an earlier trial.
The offences were committed by Bolton, from Balfour Street in East Bowling, over a period of more than thirty years with the youngest victim being just six at the time she was sexually abused.
Detectives at the Bradford District Safeguarding Unit opened a case against Bolton in February 2017, after a woman contacted police to say she had been sexually abused by him.
The ensuing investigation uncovered three more victims and Bolton was charged late last year with multiple offences.
Detective Constable Andrew Penn, who led the investigation into Bolton’s offending, said: “I would like to thank the victims for their bravery in coming forward to report Bolton’s abuse and hope that today’s outcome will give them some closure and allow them to move forward with their lives.
“I also hope it will give other victims the confidence to engage with the Bradford District Safeguarding Unit, knowing that every report they make will be taken seriously and investigated thoroughly so they can be protected from further harm and action can be taken against perpetrators.”
An NSPCC spokesman said: “Bolton is a truly evil individual who has shown no remorse for his sickening actions, and we hope today’s sentencing brings some form of closure for his victims.
