Three adults and a child sustained serious injuries after being attacked in south Armagh.
The incident happened in the Cullyhanna area on Friday morning.
Police are investigating the incident but it is not believed to have been sectarian.
One man remains in a stable condition in Daisy Hill Hospital in Newry.
It happened at a building site in the Cullyhanna area, with the victims being a woman and her young child, together with a male relative and another man.
They were set upon by a gang wielding a shovel and a wheel brace.
Two of the adults and child were treated at hospital and have since been discharged.
Local SDLP Assemblyman Justin McNulty said he has spoken to the family.
He condemned those behind the attack, which he described as “vicious”.
Mr McNulty said: “I’m totally horrified by this vicious attack that left three adults and a child seriously injured.
“This vicious assault can never be justified or rationalised and the victims are at a complete loss as to why they were targeted.
“I have been told that the victims were at the building site of a new house when they were confronted by three men wielding a shovel and a wheel brace.
“When their attackers realised that there was a young child in the car, they smashed the windows in showering the infant with glass.
“I have spoken to the family who have been left extremely traumatised.
“An attack like this is beneath contempt and reminds us of the worst days of our past.
“This community is rightly appalled and we all hope that the PSNI are successful in apprehending those responsible.
“I appeal to anyone in the local area who has any information which may assist the police with their inquiries to come forward with it without delay.”
