The man is in hospital with non-life-threatening injuries after the incident at his home on Talbot Street, Fingal, just after midnight on Tuesday, investigators said.

Acting Detective Inspector John Parker said the victim was asleep in bed when the three women broke into his home, entered his room and demanded money from him.

"One of the main offenders has punched and kicked him and hit him with a wooden object of some type, described as a club," Acting Detective Inspector Parker said.

"He has fought those several females … they've tried to tie him up unsuccessfully, they've threatened they would shoot him.

"He fought them off as much as he could, he punched and kicked them, it's quite possible that they may have some bruising and injuries to their bodies."

The women left empty-handed, with the 76-year-old raising the alarm.

"He's had smashed teeth, a significant laceration to his head and has bruising on his body," Acting Detective Inspector Parker said.

'Significant ordeal' for victim

Police have said it is unclear whether the offenders knew the man.

"They were demanding money and they obviously expected him to have money but he did not have money and they did not leave with money."

The women had their faces covered during the attack, police said.

Police urged anyone with information to come forward.

"It would be a very significant ordeal for this particular gentleman, it would be very traumatic for him," Acting Detective Inspector Parker said.

"Being aged 76, being frail, in his own home, having this type of attack upon him is very terrifying."

The main offender is described as being about 50 years old, tall, with a solid build.

The second female is described as being aged between 30 to 40 and the third between 20 and 30.
