Minister for Health Leo Varadkar has confirmed he became aware of allegations of abuse at a foster home in late 2014.

Mr Varadkar said he received a letter from a whistleblower detailing sex abuse allegations at the foster care home in the south east.

He said he followed up with a meeting at an official level with Minister of State Kathleen Lynch and one of the whistleblowers in early 2015.

The Minister said: “The first thing we sought to establish was that nobody was still being put in risk and we did establish that right away that nobody was still being put at risk.

“That was the most important thing. Anything else was about investigating what happened in the past. Two investigations had already occurred or were occurring at that stage.”

The Dáil’s Public Accounts Committee (PAC) has heard how a young woman, who has an intellectual disability and was left for almost 20 years in a foster home which was the subject of serious concerns over sexual abuse.

’Grace’ had been placed there in 1989 and remained there until 2009, despite the fact that other foster children had been removed by 1996.

The Government has agreed in principle to establish a Commission of Investigation into the allegations.

Mr Varadkar said he has been informed by the Health Service Executive director general Tony O’Brien that the key people involved in keeping ‘Grace’ in the home no longer work in the public service.

“There are people who may have had a role on other levels who have roles in Tulsa and the HSE as well. Anybody in every walk of life should reflect on the decisions they make and consider what the right thing to do is but at the same time to not forget these are still allegations and allegations have to be properly investigated,” he said.

“People have a right to a fair hearing.”

Mr Varadkar said people must be held accountable but it should not be the media or politicians who make that judgement.
