A woman was threatened in front of two young children by two masked men - one armed with a hatchet - in what police believe may be a case of mistaken identity by paramilitaries.
It happened at a house in the Fernagh Gardens area of Newtownabbey on Monday.
It was reported that around 9.15am, two men, one armed with a hatchet, forced entry to the house as the female occupant was sitting in the living room with two young children.
One threatened the woman before they both left the property. The occupants were uninjured but left badly shaken.
The first man is described as being 5ft 6ins in height, of stocky build with a tattoo on his left leg.
The second man is described as being slightly taller and of slim build. He was wearing a dark tracksuit and a balaclava.
Detectives are investigating the possibility that the incident, which it is believed may be paramilitary-linked, was a case of mistaken identity.
