Two robbers knocked a man unconscious and locked three women in the boot of a car during a house burglary in south Dublin.

The raiders burst into the house in Killiney shortly after 11pm last night.

They knocked the man out before tying up his wife, daughter and her friend and locking them in the boot of what is understood to have been the family car, which was parked outside.

The robbers made their getaway with what Gardaí described as a small amount of personal property.

The man regained consciousness a short time later and raised the alarm.
