A gang of up to four masked armed raiders broke into a house in Bluetown, Allenwood yesterday evening.
It's understood the couple, who were home at the time, heard the dogs barking at around 8.30pm and one of them went to the door to see what was going on. They were confronted by the intruders who ordered them back into the house and tied them up.
The men had their faces covered and were carrying weapons. It's believed they took a quantity of cash and left the house at approximately 9.30pm.
It's not yet clear what kind of vehicle the intruders were using as the investigation is at a very early stage.
Gardai are appealing for anyone who saw anything suspicious in the Bluetown area from around 7.30pm onwards yesterday evening to contact them at Naas Garda Station on (045) 884 300.
It's understood the couple were not seriously injured in the incident, but they did receive minor injuries and were traumatised by the violent break-in.
