A man in his 30s was taken to hospital after being assaulted by three masked men, armed with a hammer and a metal bar, at a house in Ballymena.
Two women, aged in their thirties, also sustained minor injuries during the incident which happened at Lanntara.
When leaving the property, the men also smashed windows.
Detectives in Ballymena are investigating the aggravated burglary which occurred during the early hours of this morning (Tuesday 14 April).
Detective Sergeant Lenaghan said police received a report after midnight that three masked men, armed with a hammer and a metal bar, arrived at an address in Lanntara just minutes earlier.
“They made their way inside the property where there were five people – three men and two women.
“Once inside, they assaulted one of the men, aged in his thirties. He sustained injuries to his head and arm and was taken to hospital by the Northern Ireland Ambulance Service,” he said.
Two men, aged 35 and 45, have since been arrested on suspicion of aggravated burglary with intent to commit grievous bodily harm, and they both remain in custody this morning.
“This was a savage attack for which there is no justification and we are working to establish a motive. We believe it also linked to a report at 00:20am where windows of a property in the same area were also smashed. No injuries were reported.
“I want to appeal to anyone with information which could help our investigation to call us on 101 and quote reference number 59 of 14/04/20. Alternatively call Crimestoppers on 0800 555 111,” added Detective Sergeant Lenaghan.
