The ISPCC yesterday moved to restore confidence in the organisation following the arrest on Thursday night of a senior official in a fraud investigation.
Meanwhile, an attempt is to be made in the Seanad next week to get the Government to commit itself to the speedy introduction of a Bill to regulate charities.
The ISPCC official, who spent the night in Harcourt Terrace Garda station in Dublin, was released yesterday and a file is being prepared for the Director of Public Prosecutions.
While the Garda investigation was prompted by a Sunday Business Post report about the undercounting of money in Childline collection buckets in December, it is understood the investigation is not confined to these incidents.
Information is understood to have been given to gardai about alleged irregular financial practices in the organisation in the years before the Sunday Business Post investigation.
O Tighearnaigh, said it was "routine" and expressed confidence it would find nothing wrong.
Mr Paul Gilligan, the society's director of services, is expected to play a pivotal role in the creation of any new management structures which might be implemented in the wake of a review announced yesterday by the national executive of the ISPCC.
The review will be carried out by the management consulting division of accountants Deloitte & Touche who were appointed on Thursday and who will meet the ISPCC's non-executive chairwoman, Ms Mary Bennett, on Monday morning.
It is understood Ms Bennett will be pressing for a speedy review and for the early implementation of any changes arising from it.
A further statement may be made by Ms Bennett or the national executive today about interim arrangements arising from the week's events.
Mr Gilligan will receive a report from a group which is to be appointed to talk to volunteers and former volunteers about their concerns and complaints.
The group will be headed by the assistant director of services, Ms Grace Kelly, and will include a current ISPCC volunteer, a health board representative, who observers expect will be from the North Eastern Health Board, and a voluntary sector representative who, it has been speculated, will be Ms Olive Braiden of the Dublin Rape Crisis Centre.
That group will report to Mr Gilligan, who will direct a "swift" response to its findings.
The group is expected to look at concerns about fund-raising - the ISPCC yesterday apologised again for trying to compel volunteers to sell £100 tickets - and at the perception among some volunteers that the society could be autocratic in its approach to them.
The staff of the ISPCC, about 60 in all, were yesterday said to be "devastated" by the arrest of the senior official.
The official yesterday asked the national executive for leave of absence, and this was granted.
"The employee, who staunchly asserts his innocence and who denies any wrongdoing, has informed us that he believes it is in the best interests of the society and the services it provides that he should absent himself for the present," said yesterday's ISPCC statement.
"The society greatly appreciates this gesture and has agreed to grant the employee paid leave."
In a statement yesterday, the Progressive Democrats Senator, Ms Mairin Quill, said she would press the Government when the Seanad resumes on Wednesday to speed up the introduction of the "long overdue" Charities Bill.
"Millions of pounds are collected each year, yet there is no law to regulate the business and set down proper regulations that would demand proper monitoring and accountability," she said.
