Gardaí say the investigation into the activities of convicted paedophile Kieran Creaven has led to five children in the Philippines being taken to places of safety.
The former RTÉ Sports producer refused to help gardaí identify any of the children he sexually abused online or in person in Ireland, the UK or the Philippines.
Detectives at the Garda's Online Child Exploitation Unit are still trying to identify some of the children Creaven was in contact with in Ireland and have appealed for anyone with information to contact them.
The 59-year-old is now serving a ten-year sentence for sexually abusing eight children online and in person between 2014 and 2017 in Ireland and the Philippines.
None of his victims would speak of their experiences when asked to make a victim impact statement, and gardaí have been unable to identify and find a girl in the Philippines who Creaven filmed as he sexually abused her.
They are also still trying to identify some of the children in Ireland whom he had been in contact with on mainstream social media platforms including Facebook and Skype.
However, detectives examined these communications and Creaven's financial transfers and as a result were able to identify an address in the Philippines where he had sent money after he had sexually abused children there.
He paid €40 for the abuse of some children in Manila and when his credit card failed to work on another occasion he sent over dollars.
Officers at the Online Child Exploitation Unit worked with Interpol and the police in the Philippines and as a result of the investigation, five children who were victims of child sexual abuse were rescued at that address and repatriated to places of safety.
Creaven refused to co-operate with the garda investigation and failed to give them information to help identify any of his victims.
While the Creaven investigation has been completed, gardaí say they are open to anyone with information about him or any more of his victims coming forward.
