A man has been left with serious head injuries after being attacked by a gang armed with hammers in a paramilitary-style assault.
The attack happened in the Bangor Road area of Newtownards at around 8.45pm on Thursday.
Police said a gang of masked men wearing high-visibility jackets and armed with hammers entered a house and assaulted a man in his 20s.
The victim was later taken to hospital for treatment.
A short time later, police located a vehicle suspected of being used in the attack in the Glen Estate.
Detective Inspector Nigel Snoddy appealed for anyone with any information about the attack to contact police.
“This was a brutal attack of a man in a residential area. Those involved do not represent the interests of the local community and contribute nothing to it," he said.
“There is absolutely no justification for an attack like this in our communities, and we must all work together to bring those responsible to justice and to stop this from happening to anyone else.
“If you were in the area of Bangor Road, Newtownards or Glen Estate, Newtownards last night, or if you know anything about this incident which could assist us with our investigation please, pick up the phone and call detectives at Bangor on 101 and quote reference number 2042 of 25/07/19."
