A report into child sex abuse in the Raphoe Diocese has been delayed, and will not now be released until October.
It was hoped the report would be published at some point this month.
The church-run National Board for Safeguarding Children in the Catholic Church has spent months on a review of all allegations made against priests in the Diocese.
NBSCCC Chairman Ian Elliott, who is carrying out the investigation, has now asked for more information from church authorities.
It's understood Mr Elliott has contacted the Church in Donegal seeking further information and this has created the delay.
The report will not be released until October at the earliest.
A spokesman for the Board said said it could not comment on any aspect of the report until it was published.
When the report is finalised it will be forwarded to the Bishop of Raphoe Dr Phillip Boyce, who will decide when to make it public.
Raphoe if the sixth of Ireland's 26 dioceses to have an audit into alleged sex abuse by priests carried out.
