Dyfed-Powys Police have confirmed it investigated reports of historical child sexual abuse by a monk at Caldey Island near Tenby.
The incidents happened during the 1970s and 1980s.
It is understood six women were paid compensation.
The monk responsible, named by police as Thaddeus Kotik, died during the 1990s so the force was unable to pursue a prosecution.
Commenting on allegations of child sexual abuse, NSPCC Cymru said it is 'vital' victims of child abuse come forward to seek justice.
