A second man has been arrested as part of a Cardiff murder investigation.
The 46-year-old from Grangetown is currently being questioned by officers on suspicion of murdering James Way.
Mr Way, 30, from St Mellons, was taken to the University Hospital of Wales in Cardiff just after 9am last Sunday after being found unconscious. He died a short time after arriving at hospital.
In a statement released via South Wales Police, Mr Way’s family spoke of their devastation – and renewed calls for witnesses to come forward.
They said: “James was a loving, caring son and adoring father who would go the extra mile to help us and others. He will greatly missed by us all.
“We would like the public to come forward with any information to help the police in this investigation in which James was so cruelly taken from us.”
Senior Investigating Officer Detective Inspector Mark Lewis, of the South Wales Police Specialist Crime Investigation Team, said detectives were working hard to establish exactly how Mr Way had died.
“While the arrests of two men are clearly a positive development in this investigation, I would reiterate my earlier appeal for any information,” he added.
“It is believed that an altercation has taken place in, or near, Windsor Court at Holmesdale Street, Grangetown, probably sometime between 4pm and 6pm on Saturday February 19.
“If anybody saw or heard anything suspicious in this area, I would urge them to contact us.”
A police spokeswoman added a 42-year-old man from Mynachdy who was arrested on Sunday, also on suspicion of murder, remains in custody.
Anyone with information is asked to contact the incident room at Cardiff Central Police Station on 02920 571 530 or Crimestoppers anonymously on 0800 555 111.
