Gardaí are investigating a child protection issue in the Diocese of Kilmore after a complaint was made against a priest.
The priest has voluntarily stepped aside from office while an investigation takes place in Co Cavan.
The details of the allegation made against the priest are not clear, but Bishop Leo O'Reilly said it relates to events which took place a considerable time ago.
He said the complaint raises concern in relation to child safeguarding matters and the priest has voluntarily agreed to take administrative leave while an investigation takes place.
Civil authorities have been made aware of the issue.
In a statement this morning Bishop Leo O'Reilly said it is important to stress that the priest enjoys the right to the presumption of innocence while the investigation is underway.
