Manhunt over "'unprovoked' attack in Swansea centre
Detectives are investigating after a man suffered what they said could have been a life threatening neck injury in an "unprovoked" attack in Swansea.
The 30-year-old victim had emergency surgery at Morriston Hospital after the city centre assault at about 0435 BST on Sunday.
Parts of Swansea were cordoned after the incident at the junction of Northampton Lane and Craddock Street.
Police say the attacker who ran off was believed to have a bottle.
Officers said the injured man's condition is now described as stable.
The suspect was last seen running off towards the Kingsway before he then turned left into Dynevor Place.
He is white, in his mid to late 20's, clean shaven, of medium build, and about 5ft 8ins to 5ft 10ins tall.
He hadsshort brown or mousey hair and was wearing a black long-sleeved shirt, blue trousers and white trainers.
Officers are studying CCTV footage within the city centre to establish the movements of the men.
Det Ch Insp Simon Davies, who is leading the investigation, said: "If it were not for the prompt action of police, ambulance and hospital staff then the victim would probably have died and this would now be a murder enquiry.
"Our initial enquires would suggest that this appears to have been a totally unprovoked attack and we are determined the bring the offender to justice"
