Two separate murder inquiries are underway in the North.
The first follows the death of man in west Belfast two days ago.
His body was discovered at Ardmona Parade at 8.30am on Thursday morning.
The murder investigation was launched based on the results of a post mortem carried out yesterday.
And two men are being questioned about the death of a man in his thirties in Limavady, in Derry, in the early hours of this morning.
The body of the 39-year-old was found on the Sea Coast Road in the town.
