Gardai are set to interview relatives of a nine-week-old baby to establish how she sustained serious injuries.
There are grave concerns over the tot's condition, which is critical, and the little girl continues to be treated at Temple's Street Children's Hospital in Dublin. The baby, from Co Louth, was rushed to hospital on Tuesday by ambulance after family members raised the alarm.
The newborn sustained serious head and body injuries, sources said. Investigators quickly became concerned regarding the extent of the injuries the baby sustained and do not believe it was a result of an accident.
