A murder investigation has been launched after the death of a man in the Roath area of Cardiff on Saturday.

South Wales Police want to trace a man in Oakfield Street at the time of an incident at nearby Claude Road at 02:45 BST.

He was wearing a light-coloured hooded top and trainers.

A major incident room has been set up at Cardiff Central Police Station. Police are appealing for witnesses to call 02920 571530.

Detectives want to hear from the man, who was white, or anyone who may have seen him.

He was running in the direction of the A4161 Newport Road.

They have also appealed for information from anyone who saw or heard anything suspicious in Claude Road and Oakfield Street areas on Saturday morning between 01:00-03:00 BST.

The street, part of which has been cordoned off by police, includes a number of properties which have been converted into flats and bedsits.

The dead man has not been named or formally identified at this stage.

Det Supt Stuart McKenzie, who is leading the investigation, told BBC Wales: "We have a dedicated team allocated to the inquiry.

"A team of officers are working around the clock at a major incident room.

"I would urge members of the public to come forward and help us with any information they have regarding this incident."

One resident, who did not want to be named, said he did not realise there had been an incident until he heard the BBC news.

"Then I opened the curtains and saw the police," he said.

The man described the street as "usually pretty quiet" with a mix of students and families.
