Irish police are investigating the Feb. 15 murder of a 25-year-old man from Latvia who was attacked in his home in Dublin, reports Radio Telefís Éireann.

The man, whose name was not released pending notification of next of kin, was from Rīga and had been living in Ireland since July. He was attacked about 8:30 a.m. in his rented home in the Artane district of north Dublin, media reports said.

The home was shared by several Eastern Europeans. A woman asleep in a room in the home heard the attack, locked herself in the room and called a friend, who reported the attack to police, media reports said.

The man was thought to have been working as a security guard, the Irish Independent reported.

Police reportedly are concentrating their investigation on two men who were seen outside the man’s home shortly before the attack. The Latvian was stabbed several times, apparently with a large kitchen knife found at the scene. He was pronounced dead at Beaumont Hospital in Dublin.

The police, known as the gardaí, have issued appeals to employers and to the Latvian community in Ireland for assistance in gathering information about the crime.

An estimated 23,000 Latvians, mostly recent migrants who came in search of work, live in Ireland.
