A man was arrested today in connection with a pipe bomb attack on the home of a couple and their three-year-old son.
The explosion in Carnany Drive, Ballymoney, Co Antrim, left two pieces of steel embedded in the living room.
Police said the man, who was detained following a search in the area, will face charges of attempted murder.
The family were asleep when the device detonated at around 2.30am yesterday on the window sill of their home.
Detective Inspector Nick McCaw said the crime was carried out by loyalist paramilitaries and could have proved fatal.
He confirmed two 5-inch pieces of steel entered the living room and became embedded in the ceiling and sofa.
A car in the driveway was also damaged by the bomb, which sent debris hurtling into the street.
One bolt was found 50 yards away, next to a community centre.
The family were unhurt but have been left traumatised by their ordeal.
