A total of 51 people were arrested across south and mid Wales as part of a UK-wide operation.
The six month long operation targeted people accessing indecent images of children online.
Of the 51 arrests in the force areas of Gwent, South Wales and Dyfed-Powys two were registered sex offenders. Several of those arrested had unsupervised access to children including a scout leader and a foster carer.
Other local arrests included a former police officer and a social service manager.
Charging decisions are awaited in most cases but so far 12 people have been charged with offences of possession and distribution of indecent images of children.
As a result of the operation 42 children have been protected, and 16 safeguarded within south and mid Wales.
This has been a huge operation where we have targeted numerous offenders accessing child abuse images. The majority of these people may have thought they were operating under the radar but we were able to identify them and this sends a strong message to other offenders – you will be caught.
