Gardaí investigating the murder of Kenneth O'Brien in Leixlip have arrested two men this morning.

The two men - aged in their mid-30s and mid-50s - are being detained at Leixlip and Naas Garda Stations.

The remains of Mr O’Brien were discovered at separate locations in Kildare last month.

Remains were discovered floating in a suitcase at the Grand Canal in Ardclough.

More body parts were later uncovered in the canal at Sallins by the Garda Underwater Unit.

It is believed Mr O'Brien - from Ballyfermot in Dublin - had been shot in the head before his body was dismembered.
