Two men have been arrested for withholding information in relation to the murder of Baiba Saulite.
The men are being questioned in Malahide and Coolock Garda stations in Dublin. Both men are in their early 40s and were arrested at their respective homes in Allenwood, Co. Kildare and Coolock, Dublin 5.
Gardaí investigating the murder yesterday issued a fresh appeal for information on the killing of the Latvian mother-of-two a year ago.
Detectives believe Ms Saulite was murdered by a man known to her. The chief suspect is involved in organised crime and detectives believe he paid other criminals to kill the 28-year-old from Riga.
Ms Saulite was shot dead as she smoked a cigarette in the hallway of her home in Holywell Square, Feltrim Road, Swords, on Sunday, November 19th, 2006.
Her two young sons - Ali-Alexsandra (5) and Mohamed Rami (3) - were asleep in the house when their mother was shot dead. She was buried in her native Riga in December last year.
Gardaí want to speak to anyone who was in the Holywell estate on the night of the murder.
Ms Saulite knew she was in danger. She had been threatened and was in constant contact with gardaí. Her solicitor, Swords-based John Hennessy, had been given Garda protection in the weeks before her killing.
He went abroad for safety reasons for a short period after the murder. He returned to work at his legal practice before the end of last year but he is still under armed Garda protection.
