A three-year-old boy and his mother were hit by a truck in Co Offaly yesterday when the child ran out on to the road and was pursued by his mother, according to gardaí.
The 28-year-old woman's injuries were minor but her son was last night taken from Tullamore Regional Hospital to Dublin's Beaumont neurosurgery centre.
Gardaí at Tullamore said the boy sustained a fractured skull and his condition was serious.
The accident happened on the Arden Road in Tullamore just after 4pm.
