A fourth person has been arrested by gardai investigating the murder of Mikolaj Wilk in Co Cork last year.
Polish horticulturalist Mikolaj, 35, was battered and sliced when men with machetes stormed his family home in Ballingcollig on June 10, 2018.
His wife Elzbieta, who is also in her 30s, was also treated for serious but not life-threatening injuries after the incident.
She lost the power in three fingers as she frantically defended herself and her husband.
