Police say a murder victim might have been involved in an argument with three men shortly before his death in Merseyside.
It is thought the 33-year-old man was stabbed following the row in Aintree late on Tuesday.
Police were called to Melling Avenue, near Aintree Racecourse at 11.53pm, after reports of a man lying unconscious in the road.
Paramedics treated him at the scene before he was taken to University Hospital in Aintree where he was pronounced dead.
Merseyside Police say they are treating the death as murder and believe the argument culminated in the local man being assaulted. They believe it was a targeted attack and that the victim might have been known to his attackers.
House-to-house inquiries are under way and the immediate area has been cordoned off while forensic examinations take place.
Detective Chief Inspector Andy O'Connor said:
The victim's next of kin have been informed.
A post-mortem examination will be carried out later.
