An Australian woman who was repeatedly molested by a notorious paedophile in the 1970s has revealed the disgusting letters he sent her after the abuse.

Father Thaddeus Kotik abused children visiting the Abbey on the tiny Caldey Island off the coast of Wales between 1977 and 1987.

One of his victims said she had been abused by Kotik from as early as two years old but did not report his behaviour until she was 14.

When her family moved to New South Wales, the young victim reported the actions of Kotik to a Newcastle Christian school deputy principal in 1988, the Newcastle Herald reported.

An Australian (pictured as a child with Kotik in the 1970s) woman who was repeatedly molested by notorious paedophile priest Thaddeus Kotik in the 1970s has revealed the letters he sent her

She said she was told that all people were forgiven and that she needed to pray instead of report the abuse further.

The victim also revealed details from letters Kotik wrote to her in the aftermath of some of his abuses.

He writes about working in the 'children's playground' and describes meeting a 'little fat angel who is very shy'.

One letter was written to the victim telling her he would soon reunite with her family and 'put you to bed after 12 o'clock when you will be exhausted from listening to me'.

The victim said Kotik went to great lengths to 'groom parents' who would willingly let him look after their children on the small island without realising the danger.

Kotik, who died in 1992, used chocolate from the abbey dairy and sweets to strike up relationships with girls whose families holidayed on the island.

Caldey Island draws hundreds of tourists who want to visit the Cistercian Abbey, where Kotik, a former fighter in the Free Polish Army in World War Two, worked and was ordained in 1956.

The victim's family would stay in a cottage on the island and became familiar with the Kotik and the other monks who lived in the Abbey.

In a letter to the Abbey in 2017 the anonymous victim again detailed some of her experiences with Kotik.

'Father Thaddeus was an expert at isolating the children in the family from the adults to carry out the abuse,' she wrote.

'He was also an expert in knowing how to threaten, frighten and shame the children into keeping his disgusting behaviour a secret.'

In 2018 another victim of Kotik's abuse told BBC Wales of the trauma she suffered at the hands of the monk.

She said: 'I became an alcoholic, I had an eating disorder, and I was hanging around with drug addicts and prostitutes.

'I was in relationships with violent, alcoholic men and all these terrible things nearly ended my life because I was very heavily into drink and drugs, and living with a heroin addict is pretty full on.'

'My sister said he went upstairs to pray and that's when I would have been in bed, asleep, and it all fell into place, that's when he interfered with me.'

In 2017 and 2018 a further 19 people came forward as victims of Kotik with six women so far receiving out of court settlements.

Detective Chief Inspector Jayne Butler said specially-trained police were investigating and supporting victims of the historical abuse.

She has continued to encourage other possible victims to report crimes to the force.

The head of Caldey Abbey previously issued an apology acknowledging that allegations of serious child sexual abuse made against a Cistercian monk should have been passed on to police.

Daniel van Santvoort, the abbot at the abbey said he was 'truly sorry' that allegations made against Father Thaddeus Kotik had not been reported to the authorities.
