Gardaí investigating the murder of a 21-year-old man have made a fresh appeal to eyewitnesses and associates of the killers to contact them.

Gardaí are renewing their appeal for information about the murder of Dean Johnston in Dublin, more than four-and-a-half years ago.

A 46-year-old man arrested in connection with the death of a man in Newbridge, Co Kildare in the early hours of Monday morning has been released without charge.

Gardaí are appealing for information following the discovery of a man's body in Co Kildare.
