A 29-year-old father of three died after a stabbing incident in the Knowle area of Bristol on Tuesday.
Police were called to Ilminster Avenue at about 1630 BST where they found the man suffering from stab wounds.
He was taken to the Bristol Royal Infirmary, where he was later pronounced dead.
Police are appealing for anyone who may have been in the Ilminster Avenue area at the time and may have witnessed this incident to come forward.
"He's a man from their own neighbourhood, he lives here as one of the community so this is the time for people of this community to come forward speak to the police, tell us what they know," said Detective Chief Inspector Guy Vickers who is heading the inquiry.
The stabbing is understood to have happened as the man made his way home from an event for families at a nearby youth club.
"He'd been stabbed in what looked like the jugular to me or the neck region anyway and what I didn't realise to begin with was that he'd been stabbed in the middle of his chest as well," said Dominic Costello, a friend of the victim.
The area around Ilminster Avenue was sealed off and officers conducted house-to-house inquiries.
The incident is the second stabbing in the city since a knife amnesty was declared last week.
