A man has been jailed for life for murdering a 21-year-old with a knife following a confrontation over a spilled drink.
Momodoulamin Saine, 28, was convicted of murdering Asim Khan following a trial at Newport Crown Court earlier this month.
Mr Khan, from Grangetown, died after being stabbed on St Mary Street in Cardiff city centre at about 4.50am on 21 July last year.
South Wales Police said Saine was given a life sentence, with a minimum of 24 years in prison.
Detective Chief Inspector Mark O'Shea described Mr Khan as a young man "with great potential who was much loved by his family”.
"What emerged throughout the investigation and trial was that Saine is a violent, dangerous individual who took a knife onto the streets of Cardiff," he said.
"And because of his own annoyance over something so trivial as a spilt drink, felt it necessary to engage in two violent encounters resulting in Asim's murder.
"This case has led to the most tragic of consequences for the Khan family.”
The detective thanked businesses who gave police access to CCTV, door staff who attempted to intervene and witnesses who supported the investigation.
He added: "This tragic case yet again highlights the devastating and far-reaching consequences of knife crime, and I cannot stress enough the importance of loved ones reporting their concerns if they suspect someone they know is carrying a knife or involved in knife crime.
"Speaking out could, quite simply, save a life.”
Mr Khan's brother Hamza Khan, 24, was convicted of attempting to cause grievous bodily harm with intent to Saine and will be sentenced later this month, police said.
