A Whittlesey man convicted of a number of “horrific” historical sex offences has been jailed for 15 years.

Alan Chamberlain, 65, was arrested on February 6 2015 after police received reports of him abusing three girls over a period of 34 years.

He was charged with rape of a girl aged 14 to 16, sexual assault on a girl aged 16 to 17 and ten counts of indecent assault on girls aged between five and 18. However, he denied the allegations.

The court heard how Chamberlain abused his victims between 1978 and 2012.

One of the victims was between five and 14-years-old at the time of the offending, with the abuse spanning a period of nine years.

Another was 16 at the time of the offences which lasted for a year, while the third girl was aged between 14 and 17 at the time of the abuse which happened over a period of four years.

The jury unanimously found Chamberlain, of Feldale Place, Whittlesey guilty of all charges, after just three hours of deliberation on Tuesday afternoon, following a week-long trial at Peterborough Crown Court.

He was then sentenced to a total of 15 years in prison later that afternoon.

Detective Constable Amanda Sylvester, from the Child Abuse Investigation and Safeguarding Unit (CAISU), said: “Alan Chamberlain inflicted horrific abuse on his victims which has no doubt had a lasting effect on them.

“I would like to thank the victims for their bravery in coming forward and helping us to convict their abuser – he is now in a place where he can’t harm any other children, and your actions have helped us do that.”

Anyone who has suffered abuse as a child is encouraged to contact police by calling 101. Alternatively you can visit the force website which has details of other support services www.cambs-police.co.uk/GetCloser/ChildAbuse/
