A murder investigation is under way into the death of a man following an assault at a house in Ballincollig, Co Cork.

The man has been named as 35-year-old Mikolaj Wilk.

His partner Elzbieta, aged in her early 30s, was seriously injured in the attack.

Mr Wilk, who was originally from Poland, lived in Ballincollig for several years and ran a garden maintenance business.

The attack happened when a gang of up to four men entered his home in the Maglin area shortly after 3am this morning.

Mr Wilk and his partner were taken to Cork University Hospital for treatment, where he was pronounced dead at 5.30am. 

A post-mortem examination is due to be carried out tomorrow morning.

Elzbieta's injuries are not believed to be life-threatening.

The couple's two young children, aged under six, were in the bungalow and witnessed the assault. They were uninjured.

Another woman, aged in her 30s, was also in the bungalow at the time of the attack and escaped through a window. She was also not injured in the attack.

The gang left the scene in a car, possibly a BMW Three Series, which was found burnt out at Inniskenny in Waterfall six kilometres away.

Gardaí have appealed for help in tracing the movements of the car.

The bungalow was preserved for a technical examination.

Local Fianna Fáil Councillor Daithí Ó Donnabháin has described the attack as "shocking and worrying".

Speaking to RTÉ News, Mr Ó Donnabháin said: "We have a very serious incident here where men set out in the dead of night, armed with weapons to break into a house … and to cause injury and attack a man in this manner, it is very shocking and very worrying."

An appeal for witnesses has been made, and anyone with information is asked to contact gardaí at Gurranabraher Garda Station on 021-4946200 or any garda station.

Gardaí are particularly anxious to speak to any drivers who may have dash cam footage and travelled in the Maglin, Ballincollig, Ballinora and Waterfall areas between 2am and 5am.
