Three men have been arrested in connection with the murder of a Polish man in Cork last year.

Mikolaj Wilk, who was 35, was attacked by a gang of up to four men welding machetes at the family home at Maglin, near Ballincollig in the early hours of 10 June 2018.

The inquest into his death was told that the horticulturist and landscape gardener died from haemorrhage and shock due to multiple blows with a sharp weapon associated with a traumatic brain injury.

The inquest has been adjourned pending the completion of the garda investigation.

Mr Wilk's wife, Elzbieta, had to undergo extensive surgery for defensive wounds to her hands and arms sustained during the attack.

A second woman and the couple's two children managed to escape the house uninjured.

The three men were detained following searches at two addresses in Ballincollig and at a third in Togher in Cork City earlier today.

They are being questioned at Gurranabraher and the Bridewell garda stations.

These are the first arrests in the investigation.

The suspects - who are understood to be in their 30s -  can be detained for up to seven days.
