Man admits further sex offences against children in Cambridgeshire
A 26-year-old jailed for child sex offences has been given a fresh sentence for 12 further crimes.
Aaron Collis was given an indeterminate sentence in 2009, with a minimum of five years, after admitting 11 offences relating to five girls, one as young as 18 months old.
He has admitted the other offences since being jailed.
Collis was given a five-year jail sentence, to run concurrently, at Cambridge Crown Court on Monday.
Collis, a former nursery worker, committed the 12 offences against four girls aged between three and eight, between 2002 and 2009.
They included nine sexual assaults, one indecent assault and two counts of taking indecent photographs.
Collis also asked for further offences against another 13 children, four boys and nine girls, which took place between 2001 and 2009, to be taken into consideration.
Police first became aware of his crimes after Collis lent a video camera to a neighbour, on which there was offensive footage.
The original charges in 2009 included taking indecent photographs of a child; inciting a child under the age of 13 to engage in sexual activity and three counts of assaulting a child under the age of 13 by penetration.
He also admitted possessing and distributing indecent photographs of children.
None of the charges took place at nurseries in Cambridgeshire.
Det Con Jo Crisall of Cambridgeshire Police said: "We now know of 22 victims and the fresh sentence Collis has now received reflects the gravity of his offences.
"His crimes have caused trauma and lasting consequences for his victims and their families and I hope they are able to find some crumbs of comfort by the fact justice has been done."
Police said Collis will not be released until he is no longer deemed to be a risk to the public.
