A team of more than 30 gardaí are investigating the murder of Eddie Gallagher, at Friar’s Walk, on the southside of Cork City.
They believe that a man in his 50s or 60s may have seen the killer or killers leave the scene.
Mr Gallagher had been out on Valentine’s night with his girlfriend and then got a taxi to visit a friend at a house in Friar’s Walk.
He was stabbed on the street outside the house and was found by his friend who contacted the emergency services. The attack happened shortly after 6am last Sunday.
Mr Gallagher was rushed to Cork University Hospital, but died a short time later.
Inspector Pat Lehane has appealed for the man walking along Friar’s Walk to come forward and help them with their investigation.
“He was in his 50s or 60s and wore a cap. He had a dark jumper and dark pants. He was seen walking along Friar’s Walk in the direction of the city centre at about the time the incident took place. We are very anxious that he should make contact with us as we believe he may possess some vital information,” Insp Lehane said.
Detectives have conducted a number of house-to-house inquiries in the area.
Gardaí have confirmed that they have “recovered some items” from the area which may provide clues to the identity of his attackers.
They refused to say if a weapon is among the items.
Detectives have also interviewed a number of Mr Gallagher’s friends in an effort to piece together his last movements.
The dead man was originally from Hollyhill, on the northside of the city, and had some minor convictions.
Prayers were said for him at masses in the parish yesterday.
Parish Priest Fr Pat Fogarty said Mr Gallagher, who played underage for St Vincent’s GAA Club, had come from “a family who are highly esteemed and well respected”.
“The community is shocked and saddened,” Fr Fogarty said.
Detectives are also trawling through CCTV footage taken from the general area around Friar’s Walk and an incident room has been set up at Anglesea Street Garda Station.
“We are also renewing our appeal to taxi drivers who might have been in the Friar’s Walk area between 6am and 7.30am last Sunday to contact us. They might also have seen something,” Insp Lehane said.
