Detectives have launched a murder inquiry after the death of a 33-year-old man who was attacked in his car in Glasgow.
Anthony Ferns was sitting in his blue Audi A3 in Crebar Street, Thornliebank, when he suffered a "vicious" assault.
He managed to drive a short distance to his home in Roukenburn Street and got out of his car before collapsing.
Emergency services were called to the scene at about 22:20 on Thursday and Mr Ferns was pronounced dead.
The suspect is described as white, aged between 20 and 30 year old and between 5ft 8in and 6ft tall.
He was wearing a dark-coloured tracksuit and possibly a light-coloured baseball cap.
The man ran off from the scene of the attack in Crebar Street.
A police spokeswoman said a post-mortem examination would held to establish exactly how Mr Ferns died and a report sent to the procurator fiscal.
Det Ch Insp Grant Macleod, of the Major Investigation Team, said: "Extensive police inquiries are ongoing in the area of Crebar Street and Roukenburn Street at this time.
"Officers are carrying out house-to-house inquiries and gathering CCTV footage from the local area to provide more information that will help us trace the man responsible for this vicious attack.
"The team of officers are also working to establish a motive for this crime. They are currently piecing together the victim's last known movements to find out as much information as possible on the circumstances surrounding this death."
Det Ch Insp Macleod said everything was being done to catch the killer as quickly as possible.
"Extra police patrols are in the area and members of the public are encouraged to speak to a police officer if they have any concerns," he added.
