Police are continuing to investigate the murder of 20-year-old Malachi Thomas in Grangetown, Cardiff, yesterday morning.
Officers were called to reports of a serious assault in the front garden of a house in Corporation Road just before 2am.
Mr Thomas, who lived in Butetown with his mother and sister, suffered multiple stab wounds and died at the scene.
Formal identification took place earlier today and his family are being supported by family liaison officers.
The local community is thanked for its support and patience while the investigation continues.
Detective Chief Inspector Gareth Morgan, who is leading the investigation, said: “We are doing all we can to identify and arrest those responsible for the murder of Malachi Thomas.
“Following an appeal yesterday for information and CCTV a number of people have come forward for which we are very grateful.
“We are now following up some positive lines of enquiry but as yet there have been no arrests and would appeal for anyone who has information, and has not come forward, to please call us.”
Detectives are particularly keen to hear from anyone in and around Corporation Road and Holmesdale Street who has dashcam footage, private CCTV and also anyone who may have seen or heard any suspicious behaviour, argument or assault at around 2am on Monday morning.
