A man has sustained injuries to his hand and back after reports of an aggravated burglary on Tuesday night.
Police say they received a report that three vehicles had arrived to the Mill View property in Randalstown shortly before 7.20pm on January 7.
The men, who are believed to have had their faces partially covered, entered the house armed with a samurai sword, while others had what was described as sticks or bats, it has been claimed.
Detectives are appealing for information following the "frightening ordeal".
Sergeant Lyttle said: "Shortly before 7.20pm, we received a report that three vehicles had pulled up outside a house in Mill View. A number of men, reported to have had their faces partially covered, entered the house.
"One of them was reported to be armed with a samurai sword, while others had what was described as sticks or bats.
"Once inside the property, a scuffle ensued between the suspects and a male occupant who sustained injuries to his hand and back. The suspects then fled. A woman and another man who were in the house at the time were uninjured. Damage was caused to the inside of the house during the incident.
"This was a frightening ordeal, and we are working to establish a motive for this attack.
"I want to appeal to anyone who may have been in the area, between 7.10pm and 7.20pm last night, and who saw any suspicious persons, or who saw three vehicles pull up outside a house in Mill View and who may have captured their movements on their dash cam, to get in touch with us.
"Anyone who has any information about this incident is asked to call us on the non-emergency number 101, quoting reference number 1652 of 07/01/20."
Alternatively, information can also be provided to the independent charity Crimestoppers on 0800 555 111 which is 100% anonymous and gives people the power to speak up and stop crime.
South Antrim Sinn Féin MLA Declan Kearney said: "I am shocked to hear of a brutal assault on a man in Randalstown tonight and appeal to anyone with information to fully assist PSNI inquiries."
