Five masked males dressed in dark clothing forced their way into a house on Craigs Road , outside Cullybackey, shortly before 10pm last night.
A 48 year old man has been taken to hospital for treatment to minor injuries following the aggravated burglary.
One of these men is thought to have been armed with a handgun, another with a hammer. The male with the firearm struck the victim on the head with the weapon demanding money. The gang then ransacked the property before fleeing empty handed.
Detectives are appealing for anyone with information to contact the offices of Ballymena Reactive and Organised Crime on the non-emergency number 101.
If someone would prefer to provide information without giving their name they can contact the independent charity Crimestoppers on 0800 555 111.
