Youth bailed over 'unprovoked' Swansea attack
A 16-year-old youth questioned in connection with a serious assault on a man in Swansea has been bailed.
The 22-year-old man suffered a fractured skull in the assault at Quay Parade on Saturday 4 September, which police described as "unprovoked".
The unnamed victim, who required surgery, is being treated at the University Hospital of Wales, Cardiff.
South Wales Police said its investigation was ongoing and renewed appeals for witnesses.
The injured man was discovered lying on the central reservation opposite Sainsbury's supermarket by a passing motorist at around 1050 BST.
Police said they believed a group of nine moped riders approached the man from the direction of Wind Street.
One of the riders then hit him over the head with an unknown implement, said police. They then rode off towards Eastside.
Det Insp Peter Doyle said: "The victim's condition is improving although he has sustained serious head injuries as a result of the assault."
Witnesses are asked to contact Swansea Central CID on 101 or Crimestoppers anonymously on 0800 555 111.
