Gardaí and Crimestoppers are renewing their appeal for information after a murder in Ballyboughal in north Dublin last month.
The body of 33-year-old Michal Kurek from Poland was found with multiple stab wounds at the side of the road on August 4th.
The victim had been living here since 2010, and had recently become homeless.
He is said to have frequented the Ongar area.
Gardaí are looking to speak to people living in the Ongar, Clonsilla, Coolmine, Hartstown and Huntstown areas, as well as members of the Polish community.
Detective Inspector Eddie Carroll is with Balbriggan Garda Station, and he says he 'genuinely believes' that members of the public have information about the murder.
He said: "I am asking these individuals to come forward. Information can be given to investigating Gardaí at Balbriggan Garda Station on 01 6664500 or any Garda Station.
"If a member of the public prefers to give the information without identify themselves, they can call Crimestoppers on 1800 25 00 25.”
He added that they are following "hundreds of lines of inquiry", and they are particularly looking to speak to any witnesses who saw any bloodstains in the area:
