Investigators believe the males, seen coming from the apartments in Sallins and moving towards the canal, could assist in their inquiries
Gardaí in Kildare want to speak to three men who may be able to help them solve the murder of Kenneth O'Brien.
The men were seen walking towards the Grand Canal in Sallins between 7 and 8pm on the evening of Saturday the 16th of January.
Mr O'Brien's body parts were dumped in the canal after his death.
Detectives are questioning two men arrested last weekend, but Sgt Gerry Goode told Kfm they still want to make contact with witnesses:
"We are seeking to identify three males, who may be in a position to offer us some assistance, who came from the direction of the apartments in Sallins towards the canal between 7pm and 8pm on the 16th of January (Saturday)."
