Gardaí investigating the murder of Mikolaj Wilk in Co Cork have appealed for a taxi driver, who they say was in the area of the home in Ballincollig, last Saturday night/early Sunday morning, to come forward.
The 35-year-old - who was also known as Nick - and his wife were attacked in their home at Maglin in the early hours of Sunday 10 June and a search is continuing for the gang of up to four men who attacked them.
Gardaí said they are anxious to speak to a taxi driver who picked up three women at a pub in the Wilton area, through a booking on a taxi app, and drove to Waterfall, dropping off two of the women along the way.
They have also appealed for any other taxi or hackney drivers that were operating in the Maglin, Ballincollig, Ballinora and Waterfall areas that night who have not yet come forward to do so.
Searches were conducted this morning on the route gardaí believe the gang took after they left the house.
Mr Wilk's body has been released to his family.
Gardaí have appealed for anyone with information to contact them at Gurranabraher Garda Station on 021- 4946200 or any garda station.
Mr Wilk's wife, Elzbieta, has been released from Cork University Hospital where she was being treated for her injuries and she joined in prayers for the family, along with her father and sister-in-law, at mass last night in Ballincollig.
Irish and Polish people formed a queue to express their solidarity with the grieving relatives at the mass.
Ballicollig parish priest, Fr George O'Mahony, appealed for information over the case at the mass.
Polish Chaplain in Cork, Fr Piotr Galus said the mass was very well attended and that the community was shocked by the brutality of the death.
