GARDAI investigating the death of a 10-day-old baby boy have arrested a man and a woman.
The infant, John McCarthy, died last Friday at the emergency department of Our Lady of Lourdes Hospital in Drogheda, hours after his admission.
He had sustained a head wound and a fractured arm, injuries believed to be consistent with a fall from a height.
Gardai arrested the pair, who are in their mid 20s, in Navan last night -- the man on suspicion of withholding information from gardai and the woman on suspicion of assault.
The infant had travelled with his parents from their home in Navan, Co Meath, to a house in Scholars Walk in Lusk, north Co Dublin, last Thursday night. A number of adults and at least two children were in the house.
At about midnight, the baby was taken to hospital but died around two hours later, despite the efforts of medical staff.
Witnesses told detectives the death was a tragic accident, claiming the baby fell from the arms of another child, it is believed. However, investigators still treated the death as suspicious.
The family involved are from the Travelling community. Neighbours in Lusk said they became concerned when they heard a commotion outside the house at around midnight.
A neighbour said a woman "was out in front of the house crying". She was "holding her face and looked distraught".
