It's emerged that Gardai didn't contact local social workers when they removed a two year old Roma boy from his family in Co Westmeath.
A report has found a breakdown in communication between the Gardai and the HSE was a contributing factor in the wrongful removal of the toddler.
According to the Sunday Times, officers involved used an emergency helpline to arrange accommodation for the young boy, and the HSE was not made aware of his removal until the following morning.
In the case of the removal of a 7 year old girl from her family in Tallaght, social workers didn't question gardai, who used their powers under section 12 of the Child Care Act, because they believed the issue was one of a criminal nature.
The Children's Ombudsman will now carry out her own investigation into both cases.
