The 21-year-old man who died three days after being stabbed in Fishponds has been named by police as Ronald Leigh.
The attack happened in the vicinity of Gill Avenue shortly before 7pm on Tuesday 9th October.
A forensic post-mortem has confirmed the cause of death as a single stab wound.
Detectives from the Major Crime Investigation Team are leading a murder inquiry into the incident which is also being linked to a second assault nearby on the same night.
A number of people are believed to have been involved in an incident on Downend Road at around 8.40pm which left a 48-year-old man with multiple serious injuries. He remains in a critical condition in hospital.
Three men were arrested last week on suspicion of attempted murder.
Senior investigating officer Det Insp Mike Buck said: “We’re continuing to investigate the circumstances surrounding Ronald’s death and our thoughts are very much with his family at this distressing time.
“They are being fully supported by a trained family liaison officer who will keep them updated on the progress of our investigation.
“We understand this is also a concerning time for the local community and anyone with any concerns is encouraged to contact their local neighbourhood team.”
Det Insp Buck has appealed for anyone who was in the areas of Gill Avenue and Downend Road on Tuesday night who saw the incidents, or anything else suspicious, to contact the police.
He has also asked for anyone with footage of the incidents, such as that recorded on a dash-cam.
