Gardaí are appealing for witnesses after an elderly couple were threatened at knife point in their home in Cork city.
It happened early on Sunday morning in the Gurranabraher area.
A man aged in his 70s and a woman in her 80s where threatened at knife point by a man shortly after 7.30am at their house on Boyce's Street.
The man left the scene on foot with a sum of cash.
Both victims were treated at the scene by emergency services personnel.
Their injuries are not described as life threatening.
Investigating Gardaí are keen to speak with anyone who was in the vicinity of Boyce's Street, or neighbouring streets, between 6:30am and 9:00am on Sunday who may have witnessed anything.
They are also appealing to road users with video footage from the Gurranabraher area between those times to make it available to them.
Anyone with any information is asked to contact Gurranabraher Garda station on 021-494-6200, the Garda Confidential Line at 1800-666-111 or any Garda station.
It comes after separate aggravated burglaries took place in Kildare and Sligo in the past month.
Officers investigating a serious assault on 73-year-old Thomas Niland, at his home in Skreen Co Sligo in January, have once again renewed their appeal for anyone with information to come forward.
Mr Niland remains in hospital in a critical condition.
Earlier this week, a teenage boy appeared in court in connection with a separate burglary in Celbridge in Co Kildare, which left a 72-year-old man in a serious condition in hospital.
Gardaí say investigations into the three separate incidents are continuing, and are appealing for anyone with information to contact them.
