A Lithuanian suspected of murdering two of his countrymen in Northern Ireland was today being questioned by police.
The man was arrested in Lancashire and taken back to Belfast in connection with the deaths in May.
The bodies of two men were found lying in long grass near a golf course in Warrenpoint, Co Down, in May. They are believed to have been murdered at a house in nearby Newry where a number of Lithuanian immigrants had been living while illegally working on mushroom farms in the area.
A Lithuanian woman was also arrested on suspicion of assisting offenders but has since been released without charge.
The Police Service of Northern Ireland (PSNI) and Scotland Yard are searching for a second suspect whom they believe to be in London.
A PSNI spokesman said they were seeking Mr Vitalijus Sedovas (21) somewhere in the capital.
