David Lewis named as victim of Cardiff river 'murder' as man arrested
A 28-year-old man has been arrested on suspicion of murder after the body of a man was discovered partially submerged in a Cardiff river.
David Lewis was discovered by Penarth Road bridge in Grangetown in the early hours of Thursday after South Wales Police received an anonymous call.
His parents said their "lives will never be the same again".
A post mortem examination is being held to find the cause of Mr Lewis's death.
In a statement, his parents Hetty and Glyndwr from Ystrad Mynach in Caerphilly county, said: "This is so sad. We love David so much.
"We can't believe such a thing has happened to our son."
Mr Lewis lived with his parents but would occasionally visit Cardiff, sometimes staying at the Huggard Centre hostel, said police.
Leading the inquiry, Det Supt Paul Hurley said: "His parents are understandably very distressed about what has happened to their son who they have described as a good decent man, highly intelligent and a talented musician."
Police are seeking witnesses and want to speak to anyone in the vicinity of the Taff Embankment between 19:45 and 23:45 GMT on Wednesday, March 19.
Mr Hurley said: "While an individual has been arrested and remains in custody, we are still very much appealing for witnesses.
"I would also urge anyone who may have seen suspicious behaviour or an altercation on the river bank to please contact the incident room or officers at the scene."
Officers are also keen to hear from anyone who may have seen Mr Lewis in the hours leading up to his death.
The last known sighting of him was at about 19:45 on Wednesday walking along Penarth Road near the Big Yellow Storage site.
He was wearing light blue jeans, a navy anorak style jacket and a light coloured baseball cap with the wording "cross hatch".
He may have been carrying a black holdall.
An incident room has been set at Cardiff Central Police Station and a police cordon remains at the scene on the Taff Embankment side of the River Taff.
Anyone with information is urged to call the incident room on 02920 571 530, South Wales Police on 101 or Crimestoppers anonymously on 0800 555111, quoting occurrence number 1400093541.
